Description

The invention relates to a vehicle, which can be powered or unpowered, and / or an extension for the vehicle, such as an accessory. More specifically, the invention relates to an automotive vehicle that has an extendable portion for reducing vehicle drag when the vehicle is driven, and / or the extendable portion, which can be a stand-alone addition. The invention can also enable an increase of the vehicles interior passenger cabin space and / or storage space. The invention can also reside in components e.g. an accessory of the vehicle that enable the extension and improved aerodynamics. The extendable portion can comprise a support and / or a web. BACKGROUND Known vehicles typically have fixed dimensions. Further, the frontal area of the vehicle e.g. the cross-sectional profile of the front elevation has an influence on the vehicle’s coefficient drag (Cd), which can increase fuel consumption and, ultimately, the range of the vehicle. The front area of the vehicle and the drag efficiency is even more critical at motorway speeds, at which it has the greatest effect on reducing the vehicle’s range - especially for an electric car. As the speed doubles the drag quadruples. Some vehicles are adapted to adjust their dimensions e.g. camper-vans have extendable sides, or pop-up roofs, although these are for static conditions. High performance sports cars can include adjustable spoilers for improving down-force or braking, although such solutions are typically found on vehicles seeking to improve race-track type performance. It is against this background that the present invention has been made. This invention results from efforts to overcome the problems of known vehicle configurations, which suffer from fixed dimensions and sub-optimal aero-dynamics when driven or expensive vehicle shape adjustment techniques for improving racing performance. Other aims of the invention will be apparent from the following description. SUMMARY The invention generally relates to a web and / or a vehicle having an extendable portion that is extendable from a vehicle e.g. a web. The extendable portion can extend from any side of the vehicle, including the uppermost surfaces e.g. roof, bonnet, trunk etc, and the lowermost surfaces. In particular, the extendable portion can extend the front end of the vehicle and / or from the rear end of the vehicle. The extendable portion can be a support, web or combination thereof. The extendable portion can be moved from a closed position and secured in an open position. The web and support can operate together, wherein the web is storable in the vehicle and is deployable, when the support is in its open position. When deployed, the web can be configured to extend, at least in part, between the support and / or the bodywork for defining an extension of the exterior surface of the vehicle for improving vehicle aerodynamics when the vehicle is driven with the support in a drive-position e.g. when the web is held in position while the vehicle is driven. The web, however, can be deployable and / or attachable to the vehicle for improving vehicle aerodynamics, which can be independent of the support. The web, at least in part, can be inflatable. The web can, at least in part, comprise an inflatable structure. In one aspect, the invention resides in a web for extending between a first vehicle, such as a powered vehicle, and a second vehicle, such as a trailer, wherein said web: is configured to be connectable and extendable between a body of the first vehicle, and a body of the second vehicle; is movable between a stored position, and an open position for defining an extension of the body of the or each vehicle; comprises an inflatable structure formed for shaping the web when inflated; and comprises a port for receiving a fluid for inflating the web from a deflated form to an inflated form for reducing vehicle drag when the first vehicle is driven while connected to the second vehicle with the web inflated and attached thereto. The inflatable structure can comprise a flexible material. The inflatable structure can have integral components for shaping the web. The web can have connections for attachment to the or each vehicle. The web can extend between the or each vehicle. The web can have a plurality of inflatable zones and / or the state of inflation of at least one zone is independently controllable. The web and at least one of the body of the first vehicle and the second vehicle can define a substantially coterminous surface, at least in part, therebetween. A coterminous can be a continuous and substantially smooth surface e.g. a surface configured to control e.g. inhibit drag. The web can have a port for receiving a fluid for inflating the web from a deflated form to an inflated form for reducing the drag of a vehicle when the or each vehicle is driven and / or towed with the inflatable structure inflated and attached thereto. The port can be used to control the pressure within the web, which can adjust at least one of the shape and / or rigidity of the inflated web. The integral components can comprise at least one of: an internal chamber; internal tether; external tether; seams; an internal patch; and a rib for controlling the shape of the web in an inflated form. By way of example, the integral components can be configured to control at least one of the external shape of the web and the changeable e.g. foldable portions of the web e.g. for enabling slow speed manoeuvres. The web in an inflated form can have a first cross-sectional profile and a smaller second crosssectional profile, said cross-sectional taken through the longitudinal axis of the first and / or second 3 vehicle. The differing cross-sectional profiles can be used to adjust the impact of air pressure applied at an angle against the longitudinal axis of the vehicle and / or the trailer e.g. crosswinds or turbulence. The web can comprise a plurality of modules and at least one module can be controllably inflated to adjust the cross-sectional profile of the web, said cross-sectional taken through the longitudinal axis of the first and / or second vehicle for inhibit aerodynamic drag when connected to the first vehicle and / or second vehicle during dynamic driving conditions. The web and / or modules of the web can be adjustable to change the shape of the web in response to a measurement signal received from at least one of the web, first vehicle and second vehicle. The measurement signal can comprise a signal from at least one of: road surface conditions; vehicle weight; vehicle level with respect to the surface on which it rests; oscillations in the vehicle suspension; vehicle speed; measured wind pressure that is offset from the vehicles longitudinal axis; vehicle steering angle; pressure sensors in the web and / or at least one module of the web, for determining at least one of leak detection in an inflatable section of the web, a pressure drop, a rate of inflation, a rate of deflation, levels of functional leakage and a pressure level indicative of a percentage of the maximum rated inflation pressure of the web. At least one of a first vehicle and / or a second vehicle can have a web as described and claimed herein, wherein a parameter of at least one of the web, the first vehicle and the second vehicle 10 is measurable to produce a measurement signal and / or are controllable to determine the influence of the web on the performance of the first vehicle and / or the second vehicle. The web can be connected to the first and / or second vehicle. Each of the first and the second vehicle can have a web, and said webs can be connected therebetween. The term ‘web’ can be said to describe a structure comprising a plurality of webs e.g. a web extending from the first vehicle and a web extending from the second vehicle can connect or otherwise engage to define a web structure that can be monitored and / or controlled to improve the performance of the or each vehicle. A parameter measurement can be made to determine the influence of the web on energy consumption, which includes analysing at least one of: the vehicle configuration; driving style; driving conditions; driving route; and traffic conditions for indicating whether and / or how the web can be deployed for optimum energy saving when the first vehicle is towing the second vehicle and the web extends therebetween. The shape of the web can be controlled to inhibit a detriment to dynamic driving performance cause by at least one of: crosswinds and / or buffeting from passing vehicles. The influence on performance can be determinable by monitoring at least one of yaw, roll, pitch, lateral acceleration and steering angle of the or each vehicle. The pressure within an inflatable structure of the web can be adjusted to improve at least one of yaw damping, roll, pitch, lateral acceleration and steering angle of the or each vehicle e.g. when the second vehicle is towed by the first vehicle. Braking can be applied to at least one of the wheels of the or each vehicle for inhibiting aerodynamic disturbance, such as crosswind disturbance, by applying torque vectoring. The shape of the web can be adjusted in response to the or each vehicle: turning; reversing; changing incline; or experiencing a change in wind direction with respect to the longitudinal axis of at least one of the vehicles. The shape of the web can be adjusted and / or the pressure adjusted to control the articulation of the vehicle with respect to the second vehicle e.g. trailer. Articulation can be controlled in at least one of yaw, roll and pitch. At low speeds, wherein the turning radius of the rear wheels has a smaller diameter than the front wheels, the web can be configured to deflate, at least in part, for accommodating a manoeuvre of the first vehicle with respect to the second vehicle. Additionally or alternatively, at high speeds, wherein the turning radius of the rear wheels has a larger diameter than the front wheels, the web can be configured to be inflated, at least in part, for acting as a rigid body between the first vehicle and the second vehicle for enhancing the yaw damping of the second vehicle when towed by the first vehicle. At least one of the web, first vehicle and second vehicle can be measured and / or controlled to mitigate instability caused by the vehicle approaching the zero yaw damping speed for inhibiting uncontrolled movement of the or each vehicle. The first vehicle and / or the second vehicle can further comprise: a support extendable from the front end of the or each vehicle and / or a support extendable from the rear end of the or each vehicle, the support extendable from the respective end of the vehicle between a closed position, and an open position, wherein the support extends from the vehicle and is releasably securable in said open position. The web can be movable between a stored position, when the support is in the closed position, wherein the web is storable in the vehicle, and a deployed position, when the support is in the open position, wherein the web is configured to extend, at least in part, between the support in its open position and the bodywork for defining an extension of the exterior surface for improving vehicle aerodynamics when the vehicle is driven with the support in the open position. In the deployed position, the web can be an extension of the exterior surface that defines additional interior space for the vehicle, wherein said additional interior space defines at least one of: additional cabin space for vehicle occupants; and additional storage space for luggage. The respective end of the vehicle can include at least one movable component, said movable component comprising of at least one of: a 5 hatch; an upper hatch; window; bumper, or part thereof; and bumper insert, wherein the support includes the at least one movable component. The support can comprise an extendable portion for functioning as an arm for the web. The web can be stored in at least one of: at least one movable component, said movable component comprising of at least one of: a hatch; an upper hatch; bumper; and bumper insert, wherein the support includes the at least one movable component; an extendable portion for functioning as an arm or support for the web; and at least one of the lateral sides of the vehicle adjacent the respective end. In the deployed position, a securing device can be connected between the vehicle and at least one of: the support, in the open position; and at least one movable component, said movable component comprising of at least one of: a hatch; an upper hatch; window; bumper, or part thereof; and bumper insert, wherein the support includes the at least one movable component, wherein the securing device controls movement of the support and / or the at least one movable component for inhibiting damage to the vehicle through uncontrolled movement, when driven. In another aspect , the invention resides in a vehicle having: a bodywork; and a web, said extendable from the bodywork of the vehicle and including an inflatable structure in contact with e.g. connected to the vehicle, wherein the web is formed of a flexible material having at least one integral component for shaping the web when inflated, wherein the web has a port for receiving a fluid for inflating the web from a deflated form to an inflated form for reducing vehicle drag when the vehicle is driven with the inflatable structure inflated and attached thereto. The web can be extendable from the bodywork between a stored position, and an open position for defining an extension of the bodywork. The web can include an inflatable structure and references herein to inflation and / or adjustment of the form of the inflatable structure apply to an inflatable web. The bodywork can define an exterior surface of the vehicle surrounding an interior space. The bodywork can include a front end, rear end, lateral sides, lower surface and roof e.g. uppermost surface of the vehicle. The vehicle can be an unpowered vehicle e.g. a trailer. An integral component can enable the web to form inflatable shells from the web material e.g. planar fabric. Inflation of the web can enable a dimensional transformation from a substantially flat or rolled sheet of material to a three-dimensional structure. The integral component can include at least one of a cavity, tether, channel, wall and gusset. The shape and / or pattern of the integral components e.g. their connective arrangement within the web can define the shape the web forms when inflated. The web can include quasi-inextensible fabric sheets. Inflation of at least a portion of the web can cause an anisotropic in-plane contraction, which can enable the web to have an arcuate 6 form. Interconnection between the integral components can be used to determine in-plane deformation of the web. The integral component can include a securing device, which functions like a tension cable e.g. at least one of a guy rope, rod or a torsion-bar. A securing device within the web can connect one part of the vehicle to another e.g. the support, or bumper, for example. By way of example, when one art of the vehicle is extended from the body it can be prone to movement during driving and the securing device can be configured to inhibit movement during dynamic driving conditions. The integral component can be configured to maintain the form of web when connected to vehicle exterior surface. The integral component can be configured to inhibits movement in at least one of the longitudinal, lateral and vertical directions. The web can have an outer surface, facing away from the vehicle. The web can have an inner surface facing towards the vehicle and / or an internal storage cavity defined, at least in part, but the inner surface of the web. The integral components of the web can form a three-dimensional structure connected to the outer surface and / or the inner surface. The integral components of the web can be configured between the outer surface and / or the inner surface such that the web forms a threedimensional structure. The integral structure within and / or upon the web can determine the threedimensional shape of the web. The web in the inflated form e.g. in the open position can be configured to adjust its shape in response to a change of at least one of: vehicle speed, measured wind pressure, vehicle steering angle and a determined vehicle and / or web measurement. Adjustment can be implemented using at least one of: valves, channels, compressors and control systems. The vehicle and / or the inflatable structure can include a compressor for pumping air into the port of the inflatable web. The compressor can both inflate and deflate the web. The web can have a plurality of inflatable zones. The state of inflation of the or each zone can be independently controllable. Additionally, or alternatively, the vehicle and / or inflatable can comprise a closed systems e.g. fluid is moved between high and low pressure tanks e.g. using at least one of valves, compressors and a control system to adjust the form of the web. The web e.g. inflatable structure, in the inflated form can comprise a storage space. The storage space can be internal to the inflatable structure. The storage space can be accessible via a port e.g. opening or hatch. The storage space can be an open cavity within the inflatable structure. The vehicle e.g. a first vehicle can be connected to another vehicle e.g. a second vehicle, such as a trailer. The term ‘trailer’ can be understood to be a second vehicle that is pulled or pushed by the vehicle. The web e.g. inflatable structure in the inflated form can extend between the vehicle and the another vehicle for reducing vehicle drag when the vehicle is driven connected to the another vehicle. The other vehicle can be a trailer. The trailer can be powered. The trailer is typically towed, although can be pushed in the direction of travel. The another vehicle can push and / or pull the vehicle - and vice-versa. The web can be connected to the vehicle and / or the another vehicle. The web, at least in part, can be held in position by the inflation pressure within the web applying pressure to the surfaces of the web pushing against the vehicle and / or the another vehicle. The web can extend between the bodywork of the vehicle and the bodywork of the another vehicle for defining an extension of the exterior surface of the vehicle for reducing vehicle drag when the vehicle connected to the another vehicle. The web, the bodywork of the vehicle and the bodywork of the another vehicle can define a substantially coterminous surface therebetween. The web can form a coterminous extension of the surface of the or each vehicle e.g. function as an extension of the bodywork. The web can form a coterminous extension preferably without any interruption of the airflow i.e. inhibit drag forces over the surface of the vehicle in the region at which it interfaces with the web. The region at which the vehicle and web interface can be configured to at least minimise the drag forces that may occur in the region. In other words, the web can extend from at least one of the roof, front, rear, side and underfloor area of the vehicle to reduce drag forces experience by the vehicle. The web can be configured to extend between the bodywork of the vehicle and an object attached and / or mounted to the vehicle e.g. a canoe mounted to the roof, a roof-box, or a bike-rack attached to the rear of the vehicle. The web can extend between the bodywork of the vehicle and enclose an object attached to the vehicle e.g. surround, at least in part, a roof box, of bike mounted to the roof. At least two of the web, the bodywork of the vehicle and the bodywork of the another vehicle can define a substantially coterminous surface therebetween. With an extension between the vehicle and another vehicle e.g. a trailer, the energy consumption of the powered vehicle and / or trailer when driving can be reduced. This can be achieved as a result of increased efficiency due to lowering the forces acting on the vehicle-trailer combination due to reduced coefficient of drag. Reduced drag can be achieved, at least on part, by forming a continuous, or near continuous, boundary layer between vehicle and trailer thus lowering air turbulence in at least one of the wake of the vehicle, the space between the vehicle and trailer and on the leading edge of the trailer. The associated drag forces created by the air turbulence are, therefore, lowered. Moreover, the inflatable can be used to increase the stability of the vehicle-trailer combination in dynamic driving conditions. The web can define an enclosure upon the bodywork of the vehicle e.g. the web itself functions as a storage device for receiving objects e.g. luggage therein. The web can be configured to adjust its shape to complement the shape of the object attached to the vehicle for reducing vehicle drag when the vehicle is driven 8 with the inflatable structure inflated. In other words, the web can be configured to surround or enclose, at least in part, an object mounted upon a vehicle to inhibit the increase in drag caused by carrying the object on the vehicle. The web can extend vertically e.g. vertically downwards from the lower surface. By way of example, the web can extend downwards from at least one of the front bumper, sills and rear bumper. The web can include a shield e.g. deflector for inhibiting damage caused by stone-chips or other debris in the path of the vehicle. The web can be configured to adjust its shape in response to a change of a determined vehicle measurement, said determined vehicle measurements including at least one of road surface conditions; vehicle weight; vehicle level with respect to the surface on which it rests; and oscillations in the vehicle suspension. The web can be configured to adjust its shape in response to at least one of excessive displacement of the vehicle, or vehicles with respect to each other, or the surface on which they are travelling e.g. movement as a result of undulations on the surface and / or snaking movements of the trailer. The web can be extendable from the bodywork between a stored position, wherein the inflatable structure resides within or upon the bodywork in the deflated form, and a deployed position, wherein the inflatable structure extends from the bodywork in the inflated form and is releasably securable in said deployed position. The web in the deflated form e.g. storable form can be at least one of rolled; and folded. The vehicle and / or the inflatable structure can include control components for at least one of inflating the inflatable web; and adjusting the inflated form of the inflatable structure, wherein the control components include at least one of an inflation device; a valve e.g. a check valve; a processor for receiving a determined vehicle measurement; and an actuator for adjusting the inflated form of the inflatable structure. The web can include at least one of ETFE (Ethylene Tetrafluoroethylene) film; PTFE (polytetrafluoroethylene) coated woven fiberglass; polyvinyl chloride; aramid fibre e.g. Kevlar (RTM). In another aspect, examples relate to a vehicle having a support extendable from the front end of the vehicle and / or a support extendable from the rear end of the vehicle. The support can be opened from a closed position and secured in an open position. Further, a web is provided and storable in the vehicle and is deployable when the support is in its open position. When deployed, the web is configured to extend, at least in part, between the support and / or the bodywork for defining an extension of the exterior surface of the vehicle for improving vehicle aerodynamics when the vehicle is driven with the support in the drive-position.

The bodywork defines, at least in part, the exterior surface of the vehicle, or at least an outermost perimeter of the vehicle. The vehicle can be a powered vehicle, or a trailer. The vehicle can be at least one of an automobile, flying vehicle or a vehicle configured to be driven on tracks e.g. a train. When the support is in the closed position and / or the web is in the stored position they can reside within the bodywork of the vehicle e.g. within the skin, or envelope of the vehicle. The web can be stored, at least in part, within the support. When deployed, the web and / or support can define a substantially coterminous surface with the bodywork of the vehicle. Additionally or alternatively to improving the aerodynamics of the vehicle, the support and / or the web can provide additional storage space. The storage space can be enclosable within the web and / or the support. The support can be optional. The web can be configured to extend, or attach, to the vehicle and be self-supporting.

The bodywork defines an exterior surface of the vehicle surrounding an interior space. The interior space can include a passenger cabin, luggage store e.g. boot or trunk, or a combination thereof. The bodywork of the vehicle includes a front end 12, rear end 14, lateral sides 16, lower surface 18 and roof 20 of the vehicle 10. The vehicle further includes structural components, such as pillars 22, which are commonly referred to as the A-pillar, B-pillar, C-pillar etc, depending on the type of vehicle. Bumpers 24 e.g. fenders are provided at the front end 12 and the rear end 14 of the vehicle. Lights 26 e.g. light clusters are located at the sides of each of the front end and rear end of the vehicle, and are configured to meet homologation requirements. The exterior surface can include: mirrors 28, which can include a camera; and one or more spoilers 30, which function to influence the vehicle’s aerodynamics. The vehicle 10 includes doors 32, and in the example of Figure 1 the vehicle has two doors on each lateral side, and one rear door, which is typical of a ‘hatchback’ type of vehicle, wherein the door, or hatch 32 has an upper 15 hatch 32a and a lower hatch 32b - each of which can be independently opened for ingress and egress from the vehicle. While the vehicle 10 of Figure 1 is representative of the prior art it will be used as a reference for describing examples of the invention, wherein the features of the invention preferably have no visible impact and / or influence of the vehicle’s aerodynamic properties when stored and not deployed. Figures 2(a) and (b) are, respectively, side elevation and plan views of the vehicle 10 having a support 200 extending from the rear end 14. In these Figures only one support is illustrated, although a plurality of supports can be configured to extend from the vehicle, as shown in other examples herein. In this example, the support of Figure 2(b) is configured as a platform having a depth that is less than approximately 20% of the vehicles height, and a width in the lateral direction that is between 70% and 80% of the vehicle width. The support 200 is configured to extend from the vehicle between a closed position e.g. wherein the support does not extend beyond the bodywork, and an open position, as shown, wherein the support extends from the vehicle. The support 200 can be releasably securable in said open position. The vehicle 10 further includes a web 202. The web can have a plurality of panels, and in the examples shown there is provided an upper web 202a, lower web 202b and side webs 202c. The web 202 is movable between a stored position and a deployed position. In the stored position e.g. when the support is in the closed position, the web is storable in the vehicle 10 and / or the support 200. In the deployed position, the web 202 is configured to extend, at least in part, between the support in its open position and the bodywork of the vehicle 10. In the deployed position, the web defines an extension of the exterior surface of the vehicle 10 for reducing vehicle drag when the vehicle is driven. The web, when deployed, can be described as being coterminous with the vehicle’s bodywork. The web can provide a substantially continuous extension of the bodywork while improving the vehicle’s aerodynamics by inhibiting turbulence and / or extending the length of the vehicle. The web, by defining an extension of the bodywork, can be shaped to optimise the aerodynamics e.g. configured to achieve and / or improve the coefficients of drag and / or lift. The shape of the web can be dynamic, and adjustable for different driving speeds and conditions e.g. the coefficients of drag and / or lift can be adjusted. The web can be shaped to at least one of: adjust the air pressure distribution; adjust the airflow speed; adjust airflow stagnation points; adjust airflow attachment, separation and re-attachment; adjust the boundary layer of the vehicle; adjust turbulence and vortex generation; and adjust aerodynamic characteristics at various yaw angles e.g. the wind velocity is skewed e.g. offset, from the direction of travel of the vehicle. When deployed at the front of the vehicle, the shape of the web and / or support can be configured to lower the height of the airflow stagnation point. Further, the web can be shaped to reduce drag through providing a smooth continuous curvature of the vehicle’s bodywork, said curve originating from the frontmost point of the web and / or support extension to the rearmost point of the vehicle, or the web / support extending therefrom - said curve being appreciable in at least the sideelevation view of the vehicle. The term ‘adjust’ has been used because the configuration of the web and / or support ‘adjusts the aerodynamics with respect to the vehicle without a web in place e.g. the web is substantially fixed. Furthermore, the term ‘adjust’ indicates that the aerodynamics can be changed according to speed or driving conditions e.g. the shape of the web is changeable. In other words, the web and / or support enables management of the aerodynamics. Figures 2(a) and (b) illustrate an example in which the support 200 can be implemented by an extendable portion, which can be implemented by an extendable platform and / or arm, wherein the extendable portion can be extended and / or hinged such that the volume of space occupied by the extendable portion in the stored position is less than in the open position e.g. at least 50% less. In this example the support 200 extends from a proximal point, where it is attached to the vehicle 10 and extends to a distal point from the vehicle and, in effect, extends the length of the vehicle. Extending the length of the vehicle can improve the aerodynamics in itself, while the web can be deployed from the vehicle 10 and / or the support 200 to provide a continuation of the vehicle bodywork for maintaining and preferably improving the aerodynamic efficiency of the vehicle e.g. reducing the coefficient drag of the vehicle in driving conditions. In the example of Figure 2(a), the upper web 202a extends from the distal end of the support to an area of the roof 20 that is closest to the distal end, in effect providing an extension of the roof-line of the vehicle. Similarly, the lower web 202b extends from the distal end of the support to a lowermost surface in an area of the bumper 24 that is closest to the distal end of the support, thus providing an extension of the bumper of the vehicle. Similarly, the side web 202c extends from the distal end of the support to an area of the lateral sides 16 that is closest to the distal end, in effect providing an extension of the vehicle sides. The distal end of the support 200 in Figure 2(b) is wide, thus creating a substantially rectilinear footprint in plan view, and in light of the teaching herein the web can be configured to extend between the nearest points on the bodywork and the distal end. When a single, or narrow support 200 is provided e.g. as shown in Figure 2(c), then a substantially triangular footprint is created - see Figure 8(b) for a comparable example - wherein the web extends between the nearest points on the bodywork and the distal end. Figures 3(a) and (b) illustrate an example in which two supports 200 can be implemented by extendable portions that are attached to movable components of the vehicle. The movable portions at the end 12, 14 of the vehicle can include a hatch 32, which can include an upper hatch 32a and / or a lower hatch 32b, an opening window or part of the bumper e.g. an insert of the bumper. In this example, the supports are connected via arms 200 to the bumper 24, which is displaced by the support, while the remainder of the rear end 14 of the vehicle remains in place. The bumper rests at the distal end of the support 200 in the open / deployed position. Figures 3(a) and (b) illustrate an example in which the supports 200 extend from two proximal points, where they are attached to the vehicle 10 and extend longitudinally to a distal point from the vehicle. Once again, the supports 200 and the bumper 24 attached thereto extend the length of the vehicle and, therefore, improve the aerodynamics. The web extends, in the example, from a stored position to be deployed from the vehicle 10 and / or the support 200 to provide a continuation of the vehicle bodywork for maintaining and preferably improving the aerodynamic efficiency of the vehicle e.g. reducing the coefficient drag of the vehicle in driving conditions. In Figure 3(a), the upper web 202a extends from an uppermost region of the bumper 24 to an area upon the hatch 32, thus providing an extension of the rear end 14 of the vehicle. Similarly, the lower web 202b extends from the lowermost region of the bumper 24 to a lowermost surface in an area adjacent the wheel arch, where the bumper 24 resides in a closed position. With the bumper 24 displaced from the vehicle by the support 200 the web provides an extension of the vehicle bodywork. Similarly, the side web 202c extends from the edges of the bumper to an area of the lateral sides 16 adjacent the wheel arches that is closest to the distal end and / or bumper, in effect providing an extension of the vehicle sides. Figure 3(c) illustrates that the upper web 202a can be shaped to permit the lights 26 to be viewed when the support and web are deployed, thus enabling the vehicle to meet homologation requirements using the vehicle’s lights. Figures 4(a) and (b) illustrate an example comparable to that of Figures 3(a) and (b), except that three supports 200 are provided, and said supports are, at least in part, telescopic. Further, a tray 204, which can be telescopic, is mounted and / or connected to the supports to provide a platform for holding luggage within the vehicle. Figure 4(a) also illustrates a difference with Figure 3(a) in that a greater portion of the rear end 14 of the vehicle is movably mounted to the supports - in particular, the bumper 24, lower hatch 32b and lights 26 are connected to the support and displaced from the vehicle. In this configuration, the upper web 202a extends from an uppermost region of the lower hatch 32a and light 26 to an area upon the hatch 32, thus providing an extension of the rear end 14 of the vehicle. Similarly, the lower web 202b extends from the lowermost region of the bumper 24 to a lowermost surface in an area adjacent the wheel arch, where the bumper 24 resides in a closed position. With the bumper 24 displaced from the vehicle by the support 200 the web provides an extension of the vehicle bodywork. Similarly, the side web 202c extends from the edges of the bumper to an area of the lateral sides 16 adjacent the wheel arches that is closest to the distal end and / or bumper, in effect providing an extension of the vehicle sides. The purpose of this configuration is not only to illustrate variations in the arrangement of the supports, their type and the movable portions, but that the extended vehicle can meet homologation requirements by displacing the existing lights 26 of the vehicle. Additionally or alternatively, additional lights can be configured on any of the examples herein e.g. mounted upon the support and / or movable components. Further, the web on any of the examples herein can have integrated lights and / or be transparent to enable the existing lights 26 to function to meet homologation requirements. Figure 5 illustrates an example in which the support 200 is a portion of the end of the vehicle 10 that is movable e.g. movably hinged to the vehicle, wherein the movable component can comprise at least one of, but not limited to, the hatch 32, such as the upper hatch 32a and / or lower match 32b; window; the bumper 24, or part thereof; and a bumper insert. In Figure 5 the bumper 24 is hingably connected to the vehicle in a region adjacent the wheel arch, wherein the bumper, lower hatch 32b and light 26 all tilt rearwards upon a hinge - thus functioning as a support 200 to which the web 202 extends. The movable components, therefore, function as an extendable portion, movable such that the volume of space occupied by the extendable portion in the stored position is less than in the open position. In this example the support 200 extends from the hinged point, where it is attached to the vehicle 10 and extends distally from the vehicle and, in effect, extends the length of the vehicle. The web can be deployed from the vehicle 10 and / or the support 200 to provide a continuation of the vehicle bodywork for maintaining and / or improving the aerodynamic efficiency of the vehicle. In the example of Figure 5 the upper web 202 extends between the upper hatch 32a and the lower hatch 32b, while the side web 202c extends from the edge of the support 200 e.g. the edge of the bumper 24 and lower hatch 32b to an area of the lateral sides 16 in the region of the wheel arch, in effect providing an extension of the vehicle sides. No lower web 202b is required in this configuration example. Figures 6(a) and (b) illustrate an example wherein a section 206 of the end of the vehicle 10 is mounted on two supports and displaced away from the vehicle. The format of the support 200 is not specified, and any of the supports taught herein can be used. The section 206, in this example, includes a plurality of movable components that, in effect, define the rear end 14 of the vehicle between the region of the rear wheel arch and C-pillar, and the rearmost point of the vehicle 10. In this example the support 200 extends from a proximal point, where it is attached to the vehicle 10 and extends to a distal point from the vehicle and, in effect, extends the length of the vehicle by displacing the rear end 14. Extending the length of the vehicle can improve the aerodynamics in itself, while the web can be deployed from the vehicle 10 and / or the support 200 to provide a continuation of the vehicle bodywork for maintaining and preferably improving the aerodynamic efficiency of the vehicle. In the example of Figure 6(a), the upper web 202 extends from an uppermost region of the hatch 32 to an area of the roof 20 that is closest to said uppermost region, in effect providing an extension of the roof-line of the vehicle. Similarly, the lower web 202b extends from the lowermost region of the bumper 24 to a lowermost surface in an area adjacent the wheel arch, where the bumper 24 resides in a closed position. With the bumper 24 displaced from the vehicle by the support 200 the web provides an extension of the vehicle bodywork. Similarly, the side web 202c extends from the edges of the displaced rear end 14 to an area of the lateral sides 16 adjacent the wheel arches and C-pillar that is closest to the distal end, in effect providing an extension of the vehicle sides. Figure 6(a) further illustrates an actuator 210 and a controller 100, which can operate to control movement or at least one of the support 200, web 202, movable components, section 206 and securing device 208. An actuator 210 and / or a controller 100, or a plurality thereof, can be configured to operate the inflation, deflation and adjustment of fluid pressure in the web, wherein at least part of the web is inflatable e.g. wherein the actuator 210 includes a pump e.g. an air-pump. The vehicle and / or the inflatable structure can include an actuator operating as a compressor for pumping air into the port of the inflatable web. The compressor can both inflate and deflate the web. The web can have a plurality of inflatable zones. While the controller 100 and actuator 210 are only shown in Figure 6(a), said components can be implemented in any of the examples herein and be located in the vehicle 10 and / or the web 202. The actuator 210 and / or the controller 100 can receive signals from sensors 126. Sensors can include pressure sensors for at least one of the inflatable compartments of the web 202. The sensors can be configured to detect at least one of: a leak in an inflatable section; a pressure drop e.g. caused by a fault, such as a leak, which can occur during inflation and / or dynamic operation; a rate of inflation; a rate of deflation; levels of functional leakage e.g. which occurs through imperfections in the pneumatic system; and a pressure level e.g. an indication of a percentage of the maximum rated inflation pressure of the web, or one of its portions. The sensors can provide data to a control system of the vehicle. The control system can determine a level of energy consumption required to maintain the web at an operational pressure. The control system, in conjunction with the vehicle, can determine whether the energy to maintain the web in a deployed operational condition is greater than the energy saved form having a deployed web. If the operation of the web expends more energy than it saves through aerodynamic drag reduction the control system can indicate that the web should be stored and / or operate said storing operation e.g. deflation. A predictive energy consumption algorithm can include analysing at least one of: the vehicle configuration; driving style; driving conditions; driving route; and traffic conditions to indicate whether and / or how the web can be deployed for optimum energy saving e.g. should the web be fully deployed, partially deployed or stored. The features described and shown in relation to Figure 6(a) can be implemented, in light of the teaching herein, to controllably inflate and / or deflate the web of any of the examples taught herein. Figures 7(a) and (b) illustrate, respectively, an example of the position of the support 200 e.g. when three supports are provided, with respect to the rear elevation and front elevation of the vehicle 10. The vertical position of the supports 200 is shown by way of example, and the height of the supports 200 in any of the examples taught herein can have their lowermost surface at the same height, with respect to a flat surface that the vehicle 10 sits upon, as the lowermost point of the vehicle e.g. the lowermost surface of the bumper 24, as shown. The supports 200 can, by way of example, be mounted or otherwise connected to the longitudinals of the vehicle’s body-in-white (BIW) of ladderchassis. The supports are shown extending parallel to the longitudinal axis of the vehicle by way of example only, and one or more supports can extend at an angle with respect to the longitudinal axis. A support 200 can be dimensionally configured to inhibit rotational motion about its axis. This is required to inhibit the web 202 and / or the movable components of the vehicle e.g. bumper 24 attached to and displaced form the vehicle upon the support from moving e.g. twisting during dynamic driving conditions. Additionally or alternatively, as illustrated in Figures 7(a) and (b), three or more supports 200 can be configured such that, in at least one cross-section, the supports occupy three separate and distinct non-collinear points for inhibiting rotation of the supports and / or movable portions of the vehicle 10 thereabouts with respect to the main bodywork of the vehicle. In other words, the supports, and preferably at least three supports, are configured to provide stability and inhibit uncontrolled movement of the web 202 and / or support 200. To further inhibit movement of the distal ends of the support and / or movable components of the vehicle attached thereto e.g. inhibit twisting of the extended portion of the vehicle during dynamic driving conditions, reinforcement e.g. cables, such as guy-lines can be configured to connect the bodywork of the vehicle to the extended portions for regulating movement of the support and / or movable portions with respect to the bodywork of the vehicle. At least one support 200 can be configured with energy absorbing properties, such that effect of a crash pulse from an impact e.g. in the longitudinal direction of the vehicle upon the vehicle is mitigated or otherwise reduced. The support can be configured with energy absorbing properties for absorbing offset or side impacts. Extending the vehicle using the support 200 and web 202 functions 21 to provide an absorbing barrier between the passenger cabin and / or luggage area such that the energy from a crash is dissipated, at least in part, by the collapse of the support and / or web. The examples thus far have been described in relation to the rear end 14 of the vehicle and the combinations and permutations of the support 200 and web 202 that are possible in light of the teaching herein apply mutatis mutandis to the front end 12 of the vehicle 10. All the examples herein are configured to improve at least one aspect of the vehicle’s performance while having a common features. It follows, therefore, that the features taught herein in the different examples are interchangeable, for example: the support 200 can be implemented with different quantities and / or formats of the support, e.g. three supports can extend from separate points e.g. non-collinear points; different portions of the vehicle 10 can be movable e.g. only the bumper 24 rather than the bumper 24 and lower hatch 32b can be connected to the support; movable portions of the vehicle define the support 200 e.g. the bumper is hingably attached to the vehicle; the web can be implemented using different materials and forms, as described further below e.g. different types and / or shapes of the web can be provided; the web can be configured to extend from the support and / or movable components to different portions of the vehicle bodywork e.g. to maintain visibility of the lights, or maintain visibility through the rear window; and reinforcement 208 in the form of a cable, web or combination thereof, can be used to inhibit unwanted movement of any extended portion of the vehicle during dynamic driving conditions. Moreover, examples herein can be configured such that the support and / or the web can be deployed automatically i.e. at the press of a button, or in response to another control signal, the support and web are powered between the closed / stored and open / deployed positions. In other words, the support and / or web can be moved like an automatic hood on a convertible vehicle. Additionally, or alternatively, examples herein can be configured, at least in part, such that the support and / or the web can be deployed manually. In other words, at least one of the support and the web, or its various components, can be manually deployed and secured in place. To enable automatic and / or manual configuration of the web, the support can be positioned in an intermediate position, between the closed and open position, wherein the web can be adjusted e.g. the web can be extended and secured while in the intermediate position before the support is moved to the open position wherein the web is made taut. The intermediate position can be described as an adjust-position, said adjust-position between the stored-position and deployed-position, wherein the web is connectable to the bodywork preceding the web being positioned in the deployed for defining an extension of the exterior surface. For example, in the intermediate position, the web 202 can be connected to the bodywork of the vehicle 10 e.g. edges of the web can be secure to the vehicle in at least one of: a gap between body panels; and connections e.g. press-studs, hooks, a clips, straps, magnets. In one example, a rod within the hem of the web material can be secured in a groove or recess of the bodywork. Not only can the support 200 and web 202 extend the length of the vehicle, in the deployed position, the web can provide additional interior space to the vehicle. The additional space can be an extension of the cabin space and occupiable. Additionally or alternatively, the additional space can provide storage space e.g. for luggage. The support 200, when implemented by a movable portion of the vehicle bodywork, and / or the web, can be provided with an access port, such as a door or flap, for enabling occupant and / or luggage ingress and egress from the additional vehicle interior space. The interface between the web, bodywork and / or support can be configured to provide a weathertight seal, and preferably a hermetic seal. Further, the access port can be provided with at least one of a weathertight seal and locking function to provide a secure internal space within the vehicle 10. Figures 8(a) and (b) are, respectively, side elevation and plan views of the vehicle 10 having a support 200 extending from the front end 12, and are analogous to those of Figures 2(a) and (b), except that a single relatively narrow support extends from the front end 12 of the vehicle 10. Figure 8(a) illustrates an example in which the support extends vertically downwards from the vehicle 10. While many of the examples herein disclose a support 200 in the form or an arm extending in an orthogonal direction with respect to the vehicle axes, the direction in which the support extends is not so limited. A support extending in a non-orthogonal direction can improve at least one of: the stability of the web 202 and / or movable components connected to the support e.g. the bumper; the absorption and / or deflection of energy from an impact; and improve pedestrian impact performance. Figure 8(a) shows a support 200 configured to extend from the vehicle’s front end from an uppermost region of the bumper 24 region such that its distal end extends forward and downwards towards a height level in the region of the lowermost region of the bumper. The support 200 can be releasably securable in said open position. Figure 8(b) shows the web 202 having a plurality of panels, and in the example there is provided an upper web 202a, lower web 202b and side webs 202c. The web 202 is movable between a stored position and a deployed position. In the stored position e.g. when the support is in the closed position, the web is storable in the vehicle and / or the support. In the deployed position, the web 202 is configured to extend, at least in part, between the distal end of the support 200 in its open position and the bodywork of the vehicle 10 e.g. the bumper 24. In the deployed position, the web defines an extension of the exterior surface of the vehicle 10 for reducing vehicle drag when the vehicle is driven. The web can be described as being coterminous with the vehicle’s bodywork. The web can provide a substantially continuous extension of the bodywork while improving the vehicle’s aerodynamics by inhibiting turbulence and / or extending the length of the vehicle. The distal end of the support 200 in Figure 8(b) is narrow, thus creating a substantially triangular footprint when the web extends between the nearest points on the bodywork and the distal end. The web 202 and / or support 200 can be configured to at least one of: lower the height of the airflow stagnation point; and reduce drag by providing a smooth continuous curvature originating from the front of the extension; and manage air pressure distribution e.g. to improve streamlining of airflow, reduce airflow separation, reduce vortex generation and / or reduce drag. Figures 9(a) and (b) are, respectively, side elevation and plan views of the vehicle 10 having two supports 200 extending from the front end 12, and are analogous to those of Figures 3(a) and (b), except that the support 200 and bumper 24 extend from the front end 12 of the vehicle 10. Figure 9(b) shows that the displacement of the bumper creates a substantially rectilinear footprint in plan view, and in light of the teaching herein the web can be configured to extend between the nearest points on the bodywork and the distal end. To be clear, web 202 can be configured to extend from a stored position e.g. when the support is in the closed position and the web is storable in the vehicle and / or the support. In the deployed position, the upper web 202a is configured to extend, at least in part, between an upper region of the bumper to a point on the front end 12 at a corresponding height, while the lower web 202b extends from a lower region of the bumper to a point on the front end 12 at a corresponding height. Side webs 202c extend from the side of the bumper to a point where the lateral sides 16 adjoin the front end 12 of the vehicle. As per the previous examples, in the deployed position, the web defines an extension of the exterior surface of the vehicle 10 for reducing vehicle drag when the vehicle is driven. The web can be described as being coterminous with the vehicle’s bodywork. Figures 10(a) and (b) are, respectively, side elevation and plan views of the vehicle 10 having three supports 200 extending from the front end 12, and are analogous to those of Figures 6(a) and (b), except that the support 200 and bumper 24 extend from the front end 12 of the vehicle 10. Figure 9(b) shows that one of the supports is a different dimension from the other two, and the dimensions and configurations of each support, in each of the examples herein, can be configured to be unique and independent of the others. The section 206, in this example, includes the front bumper 24 and lights and, in effect, defines the front end 12 of the vehicle between the frontmost part of the vehicle and the region of the front wheel arch and A-pillar. In this example the support 200 extends from a proximal point, where it is attached to the vehicle 10 and extends to a distal point from the vehicle and extends the length of the vehicle by displacing the front end 12. Extending the length of the vehicle can improve the aerodynamics in itself, while the web 200 can be deployed from the vehicle 10 and / or the support 200 to provide a continuation of the vehicle bodywork for maintaining and preferably improving the aerodynamic efficiency of the vehicle. This is because there is a strong correlation between vehicle length and efficient aerodynamic characteristics. This can be achieved when the web and / or support are configured to manage the airflow in a way that it reduces drag and / or lift. By way of example, the web and / or support can be configured to extend the vehicle length to implement at least one of: a well-shaped front end 12 with low stagnation point; a highly raked and curved windscreen; a curved roofline; and a long, tapered rear-end 14 of the vehicle 10. In the example of Figure 10(a), the upper web 202 extends from an uppermost region of the section 206 to an area adjacent the bottom of the A-pillar, in effect providing an extension of the bonnet i.e. hood of the vehicle. Similarly, the lower web 202b extends from the lowermost region of the bumper 24 to a lowermost surface in an area adjacent the wheel arch, where the bumper 24 resides in a closed position. Similarly, the side web 202c extends from the edges of the displaced front end 12 to an area of the lateral sides 16 adjacent the wheel arches and A-pillar that is closest to the distal end, in effect providing an extension of the vehicle sides. With the bumper 24 displaced from the vehicle by the support 200 the web provides an extension of the vehicle bodywork. Figures 11(a) to (h) illustrate different examples of web 202 storage in the support and / or vehicle. The invention is not limited to the examples herein, and the position and / or storage of the upper web 202a, lower web 202b and side webs 202c can be interchangeable. Figure 11(a) indicates that the support 200 can extend from the vehicle, and that the web 202 can be at least one of: stored in the distal end of the support, and be rolled for storage, as shown in Figure 11(b); folded such that the pleats are arranged to extend horizontally within the support, as shown in Figure 11(c); and folded such that the pleats are arranged to extend vertically within the support, as shown in Figure 11(d). Figure 11(e) indicates that the web 202 can be stored at the distal end of the support 200, and along the lateral edges of the support. Along the lateral edges of the support the web can be rolled and / or folded using a combination of the teaching in Figures 11(b) to (d). Figure 11(f) shows that format of the storage i.e. rolled or folded, can be mixed e.g. the web can be rolled at the distal end of the support, while folded along the lateral edges. In use, the web can be unfurled into the deployed position. Overall, the web is stored in at least one of: an extendable portion for functioning as an arm; and at least one of the lateral sides of the vehicle adjacent the respective end. As described above, a portion of the vehicle can define the support 200 and movably extend from the vehicle e.g. as shown in Figure 5, or a portion and / or section 206 of the vehicle can be mounted to a support 200 and be movably displaced from the vehicle e.g. as shown in Figures 9(a) and 6(a) respectively. Additionally or alternatively to storing the web in the support 200, Figures 11(g) and (h) show that the web is storable in a portion and / or section of the vehicle 10. The support 200 and / or section / portion of the vehicle 10 can have a separable element, such as a flap or a door for providing access to the web. Additionally or alternatively, a slot can be provided to permit the web to be moved between a stored and deployed position. At least one of the separable element or slot can be configured on at least one of a movable component, an extendable portion and the lateral sides of the vehicle. The web 202 can be formed, at least on part, of a manoeuvrable material that is a flexible material and / or lamella. By way of example, the flexible material can be at least one of: a fabric of woven material; and a non-woven material, both of which have manoeuvrability yet properties suitable for performing a protective function as an exterior surface of the vehicle 10. For example, the material can be made from high-density spunbound polyethylene fibres e.g. Tyvek ™. The web can comprise reinforcement material e.g. Kevlar (RTM). The flexible material can be held taut between the vehicle and the support 200, which can be a movable component of the vehicle as described herein. The form of the web 202 in the deployed condition can be held taut with additional support from at least one of cables, ropes and / or poles. The lamella e.g. an interconnectable panel, can be formed, by way of example, of sheet metal, plastic, cellulose or carbon-fibre, or a combination thereof. The lamella can include a plurality of sheets of such material. A plurality of sheets can be interlocked and / or connected to function in a telescopic manner. In use, when the support is moved from the closed to the open position, the web is caused to move from its stored position, either manually and / or automatically, into a deployed position in which it defines an extension of the vehicle’s 10 bodywork. The flexible material e.g. fabric, can be unfurled from a rolled and / or folded condition, while the lamella is manoeuvred from a stacked position. For the avoidance of doubt, a planar sheet of the flexible material can be rolled or folded like a sheet of cotton e.g. analogous to a pillowcase or tent fabric and would not be self-supporting without additional means e.g. starch, or internal structures, such as wires, if stood on its edge. Use of the flexible material can require it to be configured, at least in part, like a tent in which the flexible material is held taut between two fixing points and / or with a support, such as a rope, cable or pole. Additionally or alternatively, the flexible material, at least in part, can be inflated to become self-supporting. Further, a sheet of the lamella, while having a degree of flexibility, can be substantially self-supporting e.g. analogous to a sheet of metal, which can be rigid enough to extend vertically without support e.g. like a baking sheet or baking tray e.g. having formed edges to enhance its structural self-supporting strength. The web 202 can be a combination of materials i.e. a mix of flexible material and lamella. For example, flexible material can be used as a side web 202c and lower web 202b, while the upper web 202a can be a lamella. The lamella for the upper web 202a can have a hinged and / or lockable portion. The lamella in any of the examples herein can be comprised of a plurality of sheets of material that extend telescopically. Additionally or alternatively, the web 202 can have an inflatable section e.g. channel, which can change the web dimensions when the inflatable channel has fluid pressure applied thereto. The inflatable channel can be formed between two sheets or web material e.g. between two sheets of flexible material. By way of non-limiting example, a pump can inject air into the inflatable section. In use, the web can be deployed from its stored condition and a section of the web is inflated in the deployed condition. In the deployed condition, the inflation of a section of the web can at least one of define the shape and / or form of the web for complimenting the extension of the bodywork of the vehicle; enhance the structural strength of the web; enhance insular properties of the web e.g. thermal and / or noise insulation; and through adjustment of the fluid pressure enable the web to dynamically adjust e.g. adjust according to dynamic driving conditions. The web 202 can include a plurality of inflatable sections e.g. channels, and when inflated the fluid pressure can alter the dimensions of the web. By way of example, the pattern of the inflatable sections and / or web structures can cause the inflated web to define bespoke shapes that can compliment the vehicle’s aerodynamics. Configuring the shapes of inflatable webs is known from, at least, “Emmanuel Siefert, Etienne Reyssat, Jose Bico, Benoit Roman. Programming stiff inflatable shells from planar patterned fabrics. Soft Matter, 2020, 10.1039 / D0SM01041C. hal-03018667. Moreover, the web 202 can have a plurality of independently inflatable sections, wherein adjusting the fluid pressure in a first inflatable section and / or a second inflatable section enables the web dimensions to be changed. For example, the web can have a first form and a second form. The first form e.g. the deployed condition for normal driving conditions, wherein the support 200 and / or web 202 are deployed and define an extension of the bodywork of the vehicle. The first form can be considered as the default or primary form in which the web achieves its intended purpose e.g. for reducing vehicle drag when the vehicle is driven with the support in the drive-position. The second form, however, can be at least one of: an intermediate form, and an adjusted form. The intermediate form is different from the stored condition and the deployed condition, in which at least one inflatable section of the web has the fluid pressure adjusted such that the web can be dimensioned and / or adjustable for manoeuvring the support into position prior to the fluid pressure being adjusted for normal driving conditions. For example, the web can be unrolled, and inflated, wherein the inflation pressure displaces the support and / or movable part away from the vehicle, providing an intermediate form that permits the configuration of the open support and / or deployed web, before the fluid pressure is adjusted to dimension the web 202 in the first form. The adjusted form is different from the stored condition and the deployed condition, in which at least one inflatable section of the web has the fluid pressure adjusted such that the web can be dimensioned and / or adjustable in response to at least one of: vehicle speed; measured wind pressure that is offset from the vehicles longitudinal axis; and vehicle steering angle. For example, when the web 202 is in the deployed position and the vehicle is moving, the web dimensions can be adjusted to adjust the aerodynamics of the vehicle in response to air pressure upon the vehicle from wind direction, thus improving the vehicle’s fuel efficiency and / or stability. When the support 200 is in the open position, and the web 202 has been deployed, the connection between the vehicle 10 and the support 200, and the movable components e.g. section 206 attached thereto, can be subject to static forces and movement as well as dynamic forces and movements caused by the loading and dynamic driving conditions. To be clear, the support 200 and / or a support having a movable component mounted thereon e.g. a bumper, will be subject to forces and movements that will result in a tendency to have relative motion to the vehicle 10, constrained by the connection between the vehicle 10, the support 200 and / or the web 202 e.g. a hinge, telescopic arm, and / or bracket. To inhibit, limit and / or dampen the relative movement between the support 200 e.g. in the open position and / or the web 202 e.g. in the deployed position and / or the vehicle 10 reinforcement can be provided therebetween. Additionally or alternatively to reinforcement, clamping forces can be provided at the connections between the support 200 in the open position, and / or the web 202 in the deployed position and the vehicle 10 to inhibit, limit and / or dampen the relative movement therebetween. Additionally or alternatively to the reinforcement and / or clamping forces, compressive and / or tensile forces can be provided between the support 200 in the open position, and / or the web 202 in the deployed position and / or the vehicle 10 to inhibit, limit and / or dampen the relative movement between the support 200 in the open position, and / or the web 202 in the deployed position and / or the vehicle 10. At least one of the reinforcement, clamping forces, compressive forces and 28 tensile forces can be implemented by one or more mechanical or electromechanical means including at least one of clamps, latches, cables, bands, rope, wire, pulleys, rods, poles, pneumatic rams, hydraulic or electrohydraulic rams, pressurised chambers and / or containers, seals, bars, beams, springs, struts and by fasteners such as clips, washers, screws, pins. To inhibit, limit and / or dampen the relative movement forces and / or movement can be inhibited by at least one of the web 202 and an anchor 208, which can be implemented, by way of examples, using the aforementioned mechanical 208 or electromechanical 208 components. The anchor and / or associated attachments function as a securing device 208, and is illustrated using a hashed-line on Figures 4(a) and 4(b), Figure 5, Figures 6(a) and 6(b) - however, the securing device can be applied to any of the examples taught herein, and will be explained in relation to Figure 6(a). In one example, the securing device functions as a guy-line 208, in the form of a flexible rope 208, which is attached between the vehicle 10 and the section 206. Additionally or alternatively to the securing device functioning as a guy-line or a pole e.g. reinforcing rod can be used. To inhibit movement of the section about the connection between the support 200 and the section 206 and / or between the support 200 and the vehicle, the securing device is configured to constrain and / or restrict movement of the uppermost and / or lowermost regions of the section 206 closest to the vehicle - these points being adjacent the spoiler 30, which has a guy-line extending to the roof of the vehicle, and bottom of the bumper 24, which has a guy-line extending to a lowermost point of the wheel arch. While the support 200 holds the section 206 in position, the support 200 and / or the securing device 208 are configured to provide a forcing function between the uppermost and lowermost connection points, thus creating a multiple-point interface between the vehicle 10 and the section 206. In this example, the multiple-point interface includes three connection points, wherein the forces provide clamping, and / or compressive and / or tensile forces to inhibit and / or limit movement between the vehicle 10 and the section 206, from loading and in dynamic driving conditions. Similarly, the web 202 can function to provide clamping, and / or compressive and / or tensile forces to inhibit and / or limit movement between the vehicle 10 and the section 206, from loading and in dynamic driving conditions. The securing device 208 can be combined with the web 202. The securing device 208 can be integral e.g. embedded, at least in part, within the web 202. If the web 202 is inflatable, then different forces can be applied to the section 206. For example, the inflation pressure of the upper web 202a and lower web 202b can be adjusted to displace the uppermost and lowermost connection points of the section away from the vehicle, while the support 200 applies a force towards the front of the vehicle. In other words, in the deployed position, the securing device 208 is connected between the vehicle and at least one of: the support, in the open position; and at least one movable component, such as the section 206, said movable component comprising of at least one of: a hatch; an upper hatch; window; bumper, or part thereof; and bumper insert, wherein the support includes the at least one movable component, wherein the securing device controls movement of the support and / or the at least one movable component for inhibiting damage to the vehicle through uncontrolled movement, when driven. To be clear, the securing device 208 and / or forces applied by the web 202, can be applied in differing configurations to each of the examples herein to achieve the same functionality. Not only can the vehicle’s 10 aerodynamics be improved by the support and the web, but the extension of the exterior surface of the vehicle can define additional interior space within the bodywork of the vehicle. The additional interior space can be an occupiable space used by a vehicle occupant e.g. provide an additional passenger cabin space, or an extension of the existing passenger cabin space, or for luggage storage. The additional space can be provided at least one of: above the support; beneath the support; and between at least one movable component and the vehicle, said movable component comprising of at least one of: a hatch; an upper hatch; bumper; and bumper insert, wherein the support includes the at least one movable component. The web 202 having an inflatable portion has been described above and used in conjunction with the support 200. |The support has been described in relation to a vehicle - for the avoidance of doubt the web can extend from any portion of the vehicle, whether that be a powered vehicle, towed vehicle or an object being towed e.g. mounted upon a vehicle. Moreover, the web can extend from a support from any part of the vehicle, such as the roof, loading area e.g. pick-up bed. Additionally or alternatively a web can be used independently i.e. without a support, and extend from the vehicle 10 in a self-supporting manner when attached to the vehicle. Moreover, the web 202 can be provided as an accessory and attached to the vehicle e.g. removably connected thereto. While the web can be attached, examples herein demonstrate, by way of non-limiting examples, the application of an inflatable web 202 that is stored within the bodywork of the vehicle when deflated, and the web 202 extends from the vehicle when inflated to an inflated form. An actuator 210 and / or a controller 100 can be configured within the vehicle 10, the web 202 or both, said component(s) configured to control the deployment, retraction and modification of the web shape. To be clear, when connected to the vehicle 10 the web 202 can be: configured within the support 200, as described above i.e. the web can extend from part of the vehicle that functions as a 30 support e.g. a bumper that movable extends; and / or the web can extend from a support 200 that is not part of the bodywork e.g. a drawer as shown in Figure 4(a) or 11(a), or a bar as shown in Figure 4(a). In the following non-limiting examples the web is housed in the vehicle and deployed from an access port, which will be described with reference to a “flap” that encloses the web 202 within the access port in the bodywork when not in use. Other means of providing an access port are feasible. Figure 12 shows the vehicle 10 of Figure 1, having bodywork including the front end 12, the rear end 14, the lateral sides 16, the lower surface 18 and the roof 20. A web 202 including an inflatable structure is connected to the front end, rear end, lower surface and roof of the vehicle. The web can be removably attached to the vehicle, although in the following examples the web is stored substantially, and preferably, within an envelope of the vehicle e.g. defined by the bodywork of the vehicle when not in use. Examples herein describe a web 202 attached or connected to the vehicle and / or another vehicle e.g. a trailer. The connection, or attachment, can include at least one of: a fixing e.g. a popstud, or Velcro; a seal e.g. a magnetic seal, or a pneumatic suction seal. The interface between the web and the vehicle and / or trailer can be configured to provide a substantially continuous boundary The web can be deployed from an aperture 212, such as an access port 212. The access port can be covered by a flap 214 e.g. a covering, such as a lid, which functions to protect the web 202 when stored. References herein to the flap 214 will implicitly include the access port, although the covering 214 e.g. a flap 214 can be optional in all of the examples herein. In more detail, Figure 12 has a web 202 deployed from flaps 214 at the front end 12, rear end 14, lower surface 18 and roof 20 of the vehicle 10. Flaps 214 are not provided on the lower surface in Figure 12. The or each web can be deployed from an access port 212. At the front and rear ends of the vehicle a number plate 216 and / or associated lighting e.g. license plate is attached to the web 202. The license plate and / or lighting can be configured to be visible when the vehicle is in use e.g. to meet legal requirements. Optional supports 218 can be provided to control the position and orientation of the plate 216. The front and rear webs 202 are configured to extend the vehicle length and / or improve the aerodynamic efficiency of the vehicle when driven. The shapes of the web 202 are provided merely by way of example and not limited to the illustrations herein. The web 202 mounted on the roof is adapted to provide storage space 220 for luggage and enclose the space 220 with a lid 222 e.g. movable cover, such as a door to protect the space 220 from the environment and / or maintain aerodynamic performance. While the web 202 on the roof would typically be deployed while the vehicle was static, thus enabling luggage to be secured thereon, the webs 202 at the front, rear and lowermost areas of the vehicle can be deployed while the vehicle is being driven. For example, inflating the web 212 and / or releasing the flap 214 enables the web 202 to expand from and / or through its access port 212 into a deployed position. Overall, the web functions to improve the aerodynamic performance of the vehicle when driven. Figure 13 shows the vehicle 10 connected to another vehicle 10a, which in this example is a non-powered vehicle e.g. a trailer 10a. The another vehicle 10a has comparable features to the vehicle 10 and includes like features i.e. the bodywork of the another vehicle includes a front end 12, rear end 14, lateral sides 16, lower surface 18 and roof 20. The trailer 10a is connected to the vehicle 10 via a tow-hook 224, often referred to as a tow-hitch. A web 202 is configured to extend between the vehicle 10 and the trailer 10a. The web can extend vertically from the connection between the vehicles. It can extend to above and / or below the level of the connection to the tow-hook 224. The web 202 can be configured to function as an extension of the vehicle 10 bodywork. The web 202 can occupy the gap between the vehicles 10, 10a. The web can be shaped to improve the aerodynamics of towing a vehicle or trailer 10a e.g. by minimising drag. The web can define a substantially coterminous surface with the vehicle 10 and / or the trailer 10a i.e. the web defines, at least in part, a continuous surface between the bodywork of the vehicle 10 and the bodywork of the trailer 10a. Overall, the web 202 can be configured to occupy, at least in part, the gap between the vehicle and towed vehicle for improving at least one of the stability of the vehicle while driving and the drag coefficient. It is to be noted that the drag coefficient of a vehicle towing another vehicle when a web is provided to occupy, at least in part, the gap therebetween can be lower that the coefficient of drag of the vehicle alone i.e. when not towing. This can be achieved because the web 202 inhibits turbulence and / or pressure points e.g. air pressure points that create drag. The web extends between the vehicles to occupy the gap, or part thereof e.g. the web is coterminous with the vehicles’ bodywork and provides a substantially continuous extension of the bodywork, which reduces the number of angular edges or interfaces between the flat surfaces of the vehicles that are a source of drag-creating turbulence. By extending e.g. placing an inflatable between the vehicles the turbulence and high pressure zones are reduced. The web inhibits the generation of turbulence and high pressures at the edges or interfaces between the flat surfaces of the vehicles e.g. drag-creating turbulence can be reduced. The web 202 can be configured to attach to the trailer 10a. Additionally or alternatively the web can be inflated to press against or otherwise engage with the trailer e.g. abut against the trailer. Optional connection means between the vehicle 10, trailer 10a and the web 202 can include, by way of non-limiting example, at least one of a hook, zip, strap and hook-and-eye (e.g. Velcro (RTM)). The web in the example is shown extending from the vehicle 10 - however, the web can be configured in the trailer 10a, and extend towards the vehicle 10. It is possible that a web is stored in the rear end of the vehicle 10a and the front end 12 of the trailer, and that the inflated webs interface therebetween. The trailer 10a can include a web 202 extending rearwards. The web can be deployed from an access port 212 in the trailer, or merely attached thereto. The web can be deployed from behind a flap 214. The web can include a number plate 216 and / or support 218. The web 202 can be inflated with sufficient pressure to maintain its shape during dynamic driving conditions i.e. the pressure supports a shape that improves the aerodynamic performance of the vehicle. The web, however, can be configured to adjust its shape during dynamic driving conditions. To be clear, the web can have i) a stored position, in which it is not in use, ii) an intermediate position in which it can be partially inflated prior to being set in, iii) a deployed condition, wherein the web can be in its fully inflated form, and iv) a modified position, in which the web shape can be adjusted to accommodate dynamic driving conditions. Figure 14(a) illustrates a vehicle 10 towing a trailer 10a, wherein a web 202 substantially occupies the gap therebetween, while Figure 14(b) indicates that the shape of the web 202 is required to change in response to the movement of the trailer 10 when the vehicle is turning. The web 202, therefore, can be configured to accommodate movement by allowing and / or controlling the modification of its shape. For example, when the vehicle is turning left the web 202 on the lateral side i.e. the right-hand-side of the vehicle is required to lengthen to accommodate the movement of the trailer away from the vehicle. The web 202 in any of the examples herein can include ducting to channel airflow passing over the exterior surface of the web. The ducting can be configured to at least one of: apply an aerodynamic downforce; direct airflow for cooling e.g. over the brakes, towards a condenser of a cooling system such as an air-conditioning component, or towards animals being transported in the vehicle. The web 202 is configured for improving dynamic driving stability and / or drag. To support turning, the web 202 can include an expanded 226 e.g. an expandable portion of the web to accommodate a change of shape. Additionally or alternatively the web 202 can include, by way of example, at least one of an elasticated portion and a pleated portion, which enables a deformation to support movement of the web e.g. during turning. Different portions of the web 202 can have differing levels of elasticity e.g. the side regions can have a greater degree of elasticity to accommodate turning when the web extended between the vehicle and the trailer. When the vehicle is turning left the web 202 on the opposite side i.e. the left-hand-side of the vehicle is required to 33 shorten to accommodate the movement of the trailer towards the vehicle. The web 202 can include a foldable portion e.g. a hinge region to accommodate a change of shape. The web 202 can have at least a portion i.e. a portion of the inflatable in which the pressure is adjusted to accommodate a fold and / or compression. By way of non-limiting example, the pressure within the inflated web 202 can be adjusted to accommodate a modification of the shape e.g. on a portion that has to expand the fluid pressure within said portion can be increased, and vice-versa, wherein a portion that is required to reduce in size can involve lowering pressure. The web 202 can include features. The or each feature provided to support turning can be speed-dependent. For example, at higher vehicle speeds the features that support turning can be configured to increase rigidity. Figures 15(a) and 15(a) illustrates a scenario comparable to Figures 14(a) and 14(a), wherein a vehicle 10 is towing a trailer 10a and driving from one level to another level e.g. driving over an uneven road or driving on / off a slope. When the web 202 substantially occupies the gap between the vehicles 10, 10a then the web 202 can include an expander 226 e.g. an expandable portion of the web to accommodate a change of shape. Additionally or alternatively the web 202 can include, by way of example, at least one of an elasticated portion and a pleated portion. When the vehicles 10, 10a are on different inclines then the uppermost and lowermost surfaces, at least, are required to change to accommodate the movement of the trailer towards the vehicle. The web 202 can at least one of include a foldable portion to accommodate a change of shape and adjust the pressure to accommodate a fold and / or compression. Overall, (i) the shape of the web 202, or plurality of webs can be changed from a deployed position to a modified position, and / or (ii) the driving characteristics of at least one of the vehicle and the vehicle being towed can be adjusted. Changes and / or adjustments to at least one of the web configuration, the vehicle configuration and trailer configuration can be made to improve vehicle handling and / or safety. Changes and / or adjustments can be made to at least one of: adjust the speed of any of the vehicle and / or trailer wheels; and / or adjust the steering, in response to at least one of: vehicle speed, wherein at least one of the forces upon the web and / or the aerodynamics of the vehicle change, thus requiring a change of shape and / or a change of pressure within the inflated web; measured wind pressure upon the vehicle and / or upon the web 202 e.g. due to a cross-wind that is offset from the vehicles longitudinal axis, and at least one of the forces upon the web and / or the aerodynamics of the vehicle change, thus requiring a change of shape and / or a change of pressure within the inflated web to mitigate the change and / or tune the aerodynamic performance of the vehicle; vehicle steering angle, wherein, for example, the vehicle 10 is connected to another vehicle 10a e.g. a trailer, and an inflated web positioned between the vehicles 10, 10a 34 requires a change of shape and / or a change of pressure within the inflated web to accommodate a change in dimensions of the gap between the vehicles and, therefore manage a change in shape of the web; a determined vehicle measurement, said determined vehicle measurements including at least one of: road surface conditions; vehicle weight; vehicle level with respect to the surface on which it rests; and oscillations in the vehicle suspension; vehicle and / or towed vehicle yaw and / or pitch; at least one of speed signals e.g. from an ABS sensor signal from the or each wheel, air pressure, movement of the or each vehicle in the X, Y or Z axes and load-balancing of the vehicle being towed; and a determined web measurement, said determined web measurements including at least one of: connection status; oscillations in the web; and change of air pressure internally and / or externally within the inflated web 202. It is to be noted that the vehicle and the vehicle being towed can include features that enable improved stability and / or reduced drag. The or each vehicle can have sensors and control systems that at least one of manage damping, power the or each wheel, brake the or each wheel and recover energy through braking via the or each wheel. The or each vehicle can include a battery to power the vehicle and / or a sensing, controlling and / or inflation system. Figure 16 illustrate the vehicle 10 with respect to a crosswind, indicated by the large arrow “W”, which applies an asymmetric force upon the vehicle while driving. In response to the vehicle 10 and / or the web 202 detecting the forces of the crosswind upon the vehicle e.g. by sensing a change in pressure within the inflated web, then the shape of the web can be adjusted to alter the aerodynamic performance of the vehicle. The shapes indicated in Figure 16 are illustrated merely by way of example and other shapes of web 202 are possible for optimising the aerodynamic performance of the vehicle. When the web 202 is subject to a force that is offset from the longitudinal direction of the vehicle then the shape of the web 202 can be asymmetric to said longitudinal direction e.g. offset or asymmetrical with the longitudinal axis of the vehicle 10, 10a. Additionally or alternatively, the shape of the web 202 can be asymmetric to a vertical direction e.g. offset or asymmetrical with the vertical axis of the vehicle 10, 10a. The adjustment of the web 202 can be applied additionally or alternatively to any portion of the web 202 extending from any portion of the vehicle e.g. to the rear of the trailer shown in Figure 14. Accommodating a force that is offset from the longitudinal direction of the vehicle e.g. a crosswind can be important when the web 202 occupies the gap between the vehicle 10 and another vehicle 10a e.g. a trailer or a caravan. Vehicles towing another vehicle are susceptible to influence from dynamic driving conditions and / or external factors e.g. from cross winds that can detriment the stability of the vehicle towing and / or the vehicle being towed. During dynamic driving conditions the web 202 e.g. an inflatable web or webs can be modified in shape e.g. using a change in air pressure or air pressure distribution within an inflated web or webs. A change of shape can, by way of example, be achieved selectively inflating or deflating chambers within the web e.g. specific chambers at the surfaces of the web that require changed. At least one of the web 202, vehicle 10 and trailer 10a can be measured and / or controlled to mitigate a detriment to dynamic driving e.g. ride and handling experience cause by at least one of crosswinds, which can cause instability due to a vehicles profile - wherein the influence of said crosswinds can be determined by monitoring at least one of vehicle yaw, lateral acceleration and steering angle to identify disturbance from crosswind; and disturbance due to passing vehicles. The pressure of sections of the web can be reduced to reduce its profile and / or the stiffness can be increased the stiffness of the connection between vehicle and trailer thus making the connected vehicles a more rigid unit, which can improve yaw damping of the trailer with respect to the vehicle. While many of the examples herein refer to adjustment of the web 202, the vehicle can additionally or alternatively controlled in response to be measurements from at least one of the web 202, vehicle 10 and trailer 10a. By way of example, crosswind disturbance can be inhibited through torque vectoring by braking specific wheels, or combinations of wheels, of the vehicle and / or the trailer. Figure 17 illustrates the vehicle 10 towing a caravan 10a, wherein a web 202 occupies the gap therebetween. Webs 202 are also provided beneath the level of the tow-hook 224 on each of the vehicles. The web 202 between the vehicles above the connection e.g. tow-hood 224 is shown having a first elevation 228, wherein the web occupies the gap between the vehicles and implements a substantially continuous roofline between the vehicle 10 and the caravan 10a. A second elevation 230, indicated by different cross-hatching in the figure, is lower than the first. When experiencing a cross-wind e.g. perpendicular to the longitudinal axis of the vehicle 10, 10a the first elevation 228 can function to catch the wind e.g. like a sail, which can be undesirable. Therefore, when such a crosswind is experienced and detected by the vehicle then the web 202 can be changed to the second elevation 230, to improve vehicle stability and safety. The second elevation can have at least one of a lower profile than the first elevation; and an offset or asymmetrical profile with respect to the longitudinal axis and / or vertical axes of the vehicle 10, 10a. The shape of the web 202 in the second elevation can be such that it improves vehicle stability when towing e.g. the web 202 is shaped to apply a greater downforce. Any of the webs 202 can be adjusted from their deployed position to a modified position to improve vehicle stability. To be clear, the web 202 can have a first cross-sectional profile, with a cross-sectional profile having an upper boundary indicated by the upper-hatched area 228, and a second cross-sectional profile wherein the upper boundary is indicated by interface between the upper-hatched area 228, which has been collapsed and / or stored, and the lower hatched area 230. The web 202, which can be inflatable, can be configured from a plurality of webs 202. Figure 17 illustrates, by way of example, four different hashed areas representing different webs. The or each web 202 can be controllably inflatable and / or function like an aerofoil to inhibit drag in dynamic driving conditions. The webs 202 can be configured to inhibit drag in different areas of the space between the vehicle and trailer. The webs 202 can be configured for adaption to different vehicles and / or trailers. . The webs 202 can be configured as modular units for adaption to different vehicles and / or trailers. The adaption of the connection between (i) the web and to different vehicles and / or trailers, and / or (ii) different webs 202 can be achieved with at least one of zips, tethers, hook and eye material e.g. Velcro (RTM) and cables e.g. elasticated cables. Connections between different inflatable webs 202 can be configured to enable air pressure to be distributed and / or controlled therebetween. Elasticated sections within a web 202 and / or between webs can be configured to enable the shape of the web or webs to accommodate the different shapes or profiles of vehicles or trailers, thus making a web adaptable for different vehicle applications. The shape of the web 202 can be changed between any of its positions e.g. any one of the stored, intermediate, deployed and modified positions, using the actuator 210 and the controller 100, which can operate to control at least one of the support 200, the web 202, the movable components, the section 206 and the securing device 208. Moreover, the actuator 210 and / or a controller 100 can be configured to control the air pressure in at least one portion of the web 202 to change its shape. Sensors 126 upon the vehicle and / or within the support and / or with the web 202 can detect and measure parameters and / or control parameters. Parameters measured by sensors can include at least one of steering angle; wheel speed signals; anti-lock braking (ABS) signals from at least one wheel; air pressure e.g. at various points on the vehicle’s surface; movement of the or each vehicle in the X, Y or Z axes; load-balancing measurements derived from the vehicle being towed; accelerator signals e.g. from the accelerator pedal e.g. accelerator controls signals including at least one of position, rate of change of position, duration of position and rates of change; brake line pressures e.g. at least one of compressor pressures, individual wheel brake line pressures, absolute pressures and rate of change of pressures and related durations thereof; motor torque and / or speed e.g. at least one of absolutes, rates of change and duration; compressor and / or reservoir condition signals e.g. at least one of absolutes, rates of change and duration; valve conditions e.g. at least one of valve state i.e. open / closed, rate of change, open duration or period, temperature and pressure across the valves; temperature and pressure e.g. ambient; wind speed signals, or signals derived therefrom; battery condition signals; vehicle position signals e.g. GPS; vehicle route signals; derived signals for vehicle position / road topology; traffic signals and / or information; derived signals for aerodynamic characteristics e.g. components of drag forces, components of lift forces, centre of pressures; derived signals for road conditions; and signals derived from cameras or other such sensors detecting the presence of other vehicles and / or pedestrians e.g. LIDAR sensors. Using data from measured parameters, e.g. signals and / or data derived from the sensors 126 the controller 100 can, additionally or alternatively, can control the driving characteristics of at least one of the vehicle and the vehicle being towed. A driving characteristic that can be controlled can include at least one of: adjusting the speed of any of the vehicles’ wheels; and adjusting the steering. As described above, manoeuvrability of a vehicle and a trailer with a web 202 extending, at least in part, therebetween, requires the web to be adjustable. At least one of the web 202, vehicle 10 and trailer 10a can be measured and / or controlled to enable the web to be adjusted to improve at least one of ride, handling and safety. Adjustable webs 202 are considered, merely by way of example, in relation to Figures 14 to 19, and the associated description, which considers the dynamic requirements of a deployed web for dynamic use conditions such as reversing (Figure 14), change in incline (Figure 15) and change in wind direction (figures 16 to 18). It is to be noted that web adjustment can also be made to accommodate different shaped attachments i.e. trailers e.g. Figure 17, and storage e.g. Figure 19. When a vehicle turns, not only is the wheel trajectory between the left and right axles different, but also the traj ectory of the front and rear wheels on the same side of the vehicle body is also different. At high speeds the turning radius of the rear wheels has a larger diameter than the front wheels. At low speeds the turning radius of the rear wheels has a smaller diameter than the front wheels. Articulation can occur between the vehicle and the another vehicle e.g. a trailer. Articulation can be in at least one of yaw, roll and pitch. At least one of the vehicle, the another vehicle and the web can be monitored and / or controlled to adjust at least one of yaw, roll, pitch, lateral acceleration and steering angle of the or each vehicle for inhibiting uncontrolled movement of the vehicle and / or trailer. The control can also improve ride and handling of the vehicle for passengers and / or safety. At low speed e.g. below 30 miles-per-hour, in forward or reverse direction an inflated web can be configured to deflate, at least in part, to enable manoeuvrability of the vehicle with respect to a connected trailer. At low speeds, therefore, a web can be configured e.g. partially inflated to be flexible enough and / or be shaped to accommodate movement between the vehicle and trailer. For 38 low speed manoeuvrability the inflatable can include elasticated elements to enable the required high levels of articulation at the coupling between the vehicle and the another vehicle. In comparison, at high speeds, the vehicle and connected trailer behave like a rigid body, wherein maintaining an inflated web in a rigid state can enhance the yaw damping of the trailer and adds to the stiffness of the connection between vehicle and trailer. A web in a rigid state can provide greater stability in higher speed motorway driving and large radius turning. Stiffness can be proportional to the vehicle’s sensitivity to the weight distribution in the trailer. Yaw inertia is a key factor in the stability of a vehicle and connected trailer and, therefore, controlling the yaw inertia e.g. through yaw damping can be used to manage the vehicles sensitivity to at least one of weight distribution, crosswinds, steering and braking. It follows, therefore that a substantially rigid web between the vehicle and trailer can be used to counter yaw inertia. At higher vehicle speeds the levels of articulation e.g. articulation in yaw between the vehicle and trailer can be in the range of -25 degrees to +25 degrees. While the typical articulation is -15 to +15 degrees, it will be lower on lighter trailers (-10 to +10 degrees) and higher on heavier trailers (20 to 20 degrees on the heaviest of trailers). Higher levels of articulation occur during manoeuvres with high steering input e.g. during an emergency lane change or a ‘snaking event’, wherein the vehicle-trailer combination is travelling near to the speed of zero yaw damping for said combination i.e. yaw damping is substantially zero. During an uncontrolled manoeuvre of the vehicle and / or trailer e.g. uncontrolled snaking or a jack-knife event, the articulation in the yaw direction can increase to between 80 degrees and 150 degrees with respect to the longitudinal axis of the vehicle. Even if an inflated web is unable to be monitored or controlled to inhibit uncontrolled movement of the vehicle, it can still function to inhibit excessive and / or uncontrolled movement between the vehicle and trailer e.g. acting like an energy absorbing cushion, such as an airbag. By way of example, the inflatable web can include at least one of an adaptive vent, frangible vent and an active vent for permitting movement of the inflated web to absorb and / or control movement of the web for inhibiting uncontrolled movement of the vehicle and / or trailer. As described above, at least one of the vehicle, the another vehicle and the inflatable web can be monitored and / or controlled to keep the articulation in yaw within typical ranges. Further, at least one of the vehicle, the another vehicle and the inflatable web can be monitored and / or controlled to keep the articulation in ‘roll’ within typical ranges e.g. the vehicle rolls within a range of -10 degrees to +10 degrees, depending on vehicle and / or trailer type e.g. a typical roll articulation of a larger and heavier goods-type vehicle can be between -2 degrees and +2 degrees, while a sports-utility vehicle can have a roll angle of ± 10 degrees. Further, at least one of the vehicle, the another vehicle and the inflatable web can be monitored and / or controlled to keep the articulation in pitch controllable. Typical ranges of pitches can be within a range of -20 degrees to +20 degrees, depending on vehicle and / or trailer type e.g. a typical pitch articulation of a larger and heavier goods-type vehicle can be between -2 degrees and +2 degrees. On uneven undulating roads, or where a distance between the axles of the first vehicle and second vehicle is reduced then the pitch can greater e.g. ± 30 degrees. More practically, however, articulation in pitch using the web can be controlled to dampen oscillations in the suspension of the or each vehicle. The web can be configured to inhibit movement in the coupling between the first vehicle and the another vehicle e.g. trailer. This is because no coupling is perfect and even a small amount of movement can result in snatching or jolting, which can detriment ride and handling. At least one of the web 202, vehicle 10 and trailer 10a can be measured and / or controlled to mitigate instability caused by yaw damping approaching zero e.g. instability in an emergency or manoeuvre such as braking in a curve event e.g. turning onto a motorway slip road exit, where the roll and yaw angular accelerations are high and the speed decrease is fast. Yaw damping can tend to zero as the speed of the vehicle and connected trailer increase towards threshold speed i.e. a zero yaw damping speed, which when exceeded results in little to no damping of articulation in yaw between the vehicle and connected trailer. By way of example, a control system of the web can be configured to manage deformation of the inflatable e.g. through deflation to accommodate these levels of articulation. The web can include vanes and / or panels within the chambers that are configured to enable the passage of air therethrough to provide damping characteristic during deformation of the inflatable. Damping can be provided, at least in part, by rapid deflation of an inflated web. Additionally or alternatively, the inflatable, at least in part, can be configured to increase in stiffness at the connection between the vehicle and trailer for reducing the relative articulation between the vehicle and trailer. A combination of the added stiffness plus the damping would increase the damping at the connection, thus increasing the stability of the vehicle-trailer combination through increasing the zero yaw damping speed. Articulation can be required in at least one of yaw, roll and pitch. A vehicle can be connected to another vehicle e.g. a trailer, via a trailer hitch. A trailer hitch can be, for example, one of a drop hitch, weight distribution hitch, pintle hitch, gooseneck hitch, fifth-wheel hitch, flying saucer, ringfeder or Bartlett (RTM) e.g. a ball-socket coupling. Movement between the vehicles i.e. vehicle and trailer can articulate around the trailer hitch e.g. a single-point of connection, such as a e.g. a ball and socket coupling. An inflated web positioned between the vehicle and trailer can be monitored and / or controlled to manage at least one of yaw, roll and pitch articulation. Inhibiting uncontrolled yaw articulation can be particularly important for optimising ride and handling safety. However, inhibiting excessive roll articulation can be important e.g. while driving in crosswinds. Figures 18(a) to 18(c) show, respectively, a rear elevation, side elevation and plan view of luggage 232 e.g. a bike 232 mounted upon the roof 20 of the vehicle 10 and enclosed by a web 202. Luggage placed upon a roof of the vehicle can interrupt the airflow passing over the car while driving, and the associated drag can reduce aerodynamic efficiency and, therefore, increase fuel consumption. Drag can occur due to cross winds. While any luggage placed upon a vehicle’s roof is going to reduce aerodynamic efficiency said reduction can be minimised by reducing the turbulence caused by the luggage. The web 202 can be configured to enshroud the luggage and facilitate smooth airflow around the luggage i.e. the web creates minimal airflow disturbance around the luggage. As described in relation to Figure 16, a protrusion from the vehicle, such as the luggage 232, even when enclosed in the web 202, can function to catch the wind e.g. like a sail when a vehicle is driven while experiencing a cross-wind e.g. a force perpendicular to the longitudinal axis of the vehicle 10. As shown in Figure 18(c) the web 202 can be changed to have a modified form 230, to improve vehicle aerodynamics. The modified elevation can be offset or asymmetrical with respect to the longitudinal axis and / or vertical axis of the vehicle 10. The shape of the web 202 in modified from 230 can be such that it improves vehicle stability when luggage is mounted upon the roof. Any of the webs 202 can be adjusted from their deployed position to a modified position to improve vehicle stability. Figure 19 is a further example of a web 202, in modified form 230, can be used to enhance vehicle aerodynamics. In Figure 19 a side elevation shows the web 202 extending from an access port 212 via a flap 214, and shaped to hold luggage 232. Hashed-lines indicate the shape of the modified web 230, which can be adjusted to accommodate different luggage shapes. The web 202 can be configured to enshroud the luggage and facilitate smooth airflow around the luggage i.e. the web creates minimal airflow disturbance around the luggage. Just like Figures 16 and 18, the elevation of the web 202 in modified form 230 can be offset or asymmetrical with respect to the longitudinal axis and / or vertical axis of the vehicle 10 to optimise the vehicle’s aerodynamics. In other words, the web 202 can be modified to adjust its shape to complement the shape of the object attached to the vehicle for reducing vehicle drag when the vehicle is driven with the inflatable structure inflated around luggage. The example of Figure 19 indicates that the luggage can be place on the roof, although additionally or alternatively the web can be configured to extend from the rear end 14 and support and / or enshroud luggage e.g. a bicycle or a suitcase with a cavity 220, 234. The shape of the web 202 in any of the examples herein can be asymmetric with respect to at least one of the orthogonal axes of the vehicle 10,10a - and be configured to be asymmetric in response to at least one of: accommodate luggage; engage with another vehicle 10a; and detection of at least one of vehicle speed, measured wind pressure, vehicle steering angle and a determined vehicle and / or web measurement. Figure 20 illustrates a rear elevation view of the rear end 14 of the vehicle 10 having a web 202 extending rearwards therefrom, wherein a cross-section has been taken through the web to illustrate an example of its interior structure. The web could be inflated like a child’s party balloon e.g. having skin and inflated like a football, and define a cavity 234. In practice, the web 202 has a plurality of inflatable portions or channels 236. Said channels can be configured to define the cavity 234. By way of example, at least one tether 238 can be configured within the web to control the dimensions of the inflated web. The section in Figure 20 is split with a hashed-line indicating, for example, two different configurations of the channels: on the left, as viewed, a plurality of adjacent channels, each of which define substantially circular tubes, as viewed in cross-section, can be arranged to define a wall 240 around the cavity 234 defined by the web 202; and on the right, as viewed, the channels 236 are elongate in cross-section e.g. substantially rectilinear and, similarly, define a wall 240 around the cavity. In Figure 20 only one layer of inflatable portions defines a wall 240, although a plurality of layers can be implemented. Selectively controlled inflation of channels 236 and / or walls 240 comprising channels can determine the interior and / or exterior shape of the web 202. As described above, the web 202 can be stored flat, wherein it is rolled and / or folded. Upon deployment of the web, under the control of the actuator 210 and / or a controller 100, the channels 236 can be inflated using fluid pressure. The pressure can be controlled and / or measured using a series of values. The actuator and / or controller can include control components for at least one of: inflating the inflatable web; and adjusting the inflated form of the inflatable structure. The control components can include at least one of: an inflation device e.g. a compressor; an air tank e.g. reservoir; a valve; a processor for receiving a determined vehicle measurement; dryer for reducing the moisture content of a stored web; and an actuator for adjusting the inflated form of the inflatable structure. At least one of the web, vehicle and trailer can be configured with at least one of: a positive pressure pump and / or a reservoir for providing air to inflate the web, at least in part; and / or a negative pressure pump and / or a reservoir e.g. a vacuum for providing air to deflate the web e.g. to enable deflation in an emergency situation. The web 202 of Figure 20 is shown having channels 236, and internal cavity 234, e.g. chamber 234 and a tether 238. The tether 238 is shown as an internal component of the web, although additionally or alternatively the tether can be an external tether. The reinforcement means described above can be applied to the web 202. The web can include multiple segments secured at seems. The tether can be a sheet 242 of material extending between seems. The sheet 242 can line the cavity 234 to protect the inflatable channels 236. The cavity can define a storage space, or when extending from the vehicle in one of the examples described in relation to Figures 2 to 12 the cavity can define an extension of the interior cabin space. A movable cover e.g. a door, can be provided to permit ingress and egress from the cavity 234. While a cavity 234 has been described in relation to Figure 20, the web 202 can be configured in light of the teaching herein to define a storage space that resides, at least on part, within at least one of the vehicle and the trailer (the another vehicle). The storage space define by the web 202 can be releasably attached to the vehicle and / or the trailer. The web 202 can be stored substantially flat, and deflated, and the shape of the inflated web can be determined using computational methods e.g. the computational inverse design of surfacebased inflatables. For example, the web 202 can include an inflatable portion, said inflatable portion having two sheets of material that are bonded, fused or otherwise connected to form channels that are inflatable when pressurised e.g. heat and / or laser welding can be used to join two sheets of the web. The channels can have straight and / or curved sections. If the fused channels are not straight the inflation process functions to deform the web 202 out of plane i.e. it forms a three-dimensional shape. The formed shape can be inflated to form a structure with having stiffness. The relationship between the pattern of the channels in a deflated web i.e. the web 202 is substantially flat, and suitable for storing either flat, rolled and / or folder and has pattern of fused channels in the web 202, and the three-dimensional shape of the web in at least one of the intermediate, deployed and modified positions, is complicated. However, a web 202 can be designed using computational methods for individual applications. The design and computation of the web 202 can be achieved using differential geometry and / or physical simulation and / or sensitivity analysis. Using a web 202 comprising patterned channels can achieve negative mean curvature. The web 202 can comprise a plurality of inflatable layers, said layers comprising at least three sheets of material. An inflatable layer can be configured for each of the intermediate, deployed and modified position. The positions of the web i.e. its shape can be determined by selectively inflating and deflating the corresponding layer. The web can be inflated using a fan / blower, using cold forced-air pressure. Additionally or alternatively a gas supply can be provided. Sheets of material of the web can be sewn, fused or otherwise welded together to inhibit air leakage. However, inflatable sections can be configured to permit the bleed off of excess air pressure by design, where required. The web 202 can include additional structural features, such as: an inflatable bladder that functions as a core structure of an inflated web; tethers 238; and gussets 242 e.g. single-wall fabric reinforcements used to form custom shapes and guide the natural tendency of the air to form the required shapes. Lighting can be incorporated with the web 202 to provide illumination and / or indication e.g. required for vehicle homologation. The web can include a port for receiving a fluid for inflating the web from a deflated form to an inflated form using a compressor located in the vehicle 10, 10a and or the web 202. The vehicle and / or the inflatable structure can include a compressor for pumping air into the port of the inflatable web. The web 202 can have a plurality of inflatable zones. The or each zone can have an inflatable channel 236. The state of inflation of each zone can be independently controllable. The web 202 material can include at least one of: ETFE (Ethylene Tetrafluoroethylene) film; PTFE (polytetrafluoroethylene) coated woven fiberglass; polyvinyl chloride; and a puncture resistant material made of woven nylon e.g. a scrim bonded with a vinyl coating, wherein the two materials are pressure bonded together, and wherein the woven material inhibits rips or tears from growing. System Figure 21 is a schematic of the system 100 configured to control the or each of the components of the vehicle. The system 100 can be scalable in size to accommodate additional components adopted on to the vehicle, such as a navigation system or an entertainment system. The system 100 includes a bus 102, at least one processor 104, at least one communication port 106, a main memory 108 and / or a removable storage media 110, a read only memory 112 and a random access memory 114. The components of system 100 can be configured across two or more devices, or the components can reside in a single system 100. The system can also include a battery 116. The port 106 can be complimented by input means 118 and output connection 120. The processor 104 can be any such device such as, but not limited to, an Intel(R), AMD(R) or ARM processor. The processor may be specifically dedicated to the device. The port 106 can be a wired connection, such as an RS-232 connection, or a Bluetooth connection or any such wireless connection. The port can be configured to communicate on a network such a Local Area Network (LAN), Wide Area Network (WAN), or any network to which the system 100 connects. The read only memory 112 can store instructions for the processor 104. The bus 102 communicably couples the processor 104 with the other memory 110, 112, 114, 108 and port 106, as well as the input and output connections 118, 120. The bus can be a PCI / PCI-X or SCSI based system bus depending on the storage devices used, for example. Removable memory 110 can be any kind of external hard-drives, floppy drives, flash drives, for example. The device and components therein are provided by way of example and does not limit the scope of the invention. The processor 104 can implement the methods and perform any of the calculations described herein. The processor 104 can be configured to retrieve and / or receive information from a remote server or other device.

The indefinite articles “a” and “an,” as used herein in the specification and in the claims or clauses, unless clearly indicated to the contrary, should be understood to mean “at least one.” The phrase “and / or,” as used herein in the specification and in the claims, should be understood to mean “either or both” of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases. Other elements may optionally be present other than the elements specifically identified by the “and / or” clause, whether related or unrelated to those elements specifically identified unless clearly indicated to the contrary. Thus, as a non-limiting example, a reference to “A and / or B,” when used in conjunction with open-ended language such as “comprising” can refer, in one embodiment, to A without B (optionally including elements other than B); in another embodiment, to B without A (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc. As used herein in the specification and in the claims, “or” should be understood to have the same meaning as “and / or” as defined above. For example, when separating items in a list, “or” or “and / or” shall be interpreted as being inclusive, i.e., the inclusion of at least one, but also including more than one of a number or list of elements, and, optionally, additional unlisted items. Only terms clearly indicated to the contrary, such as “only one of’ or “exactly one of,” or, when used in the claims, “consisting of,” will refer to the inclusion of exactly one element of a number or list of elements. In general, the term “or” as used herein shall only be interpreted as indicating exclusive alternatives (i.e. “one or the other but not both”) when preceded by terms of exclusivity, such as “either,” “one of,” “only one of,” or “exactly one of.” “Consisting essentially of,” when used in the claims, shall have its ordinary meaning as used in the field of patent law. As used herein in the specification and in the claims, the phrase “at least one,” in reference to a list of one or more elements, should be understood to mean at least one element selected from any one or more of the elements in the list of elements, but not necessarily including at least one of each and every element specifically listed within the list of elements and not excluding any combinations of elements in the list of elements. This definition also allows that elements may optionally be present other than the elements specifically identified within the list of elements to which the phrase “at least one” refers, whether related or unrelated to those elements specifically identified. Thus, as a nonlimiting example, “at least one of A and B” (or, equivalently, “at least one of A or B,” or, equivalently “at least one of A and / or B”) can refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including elements other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other elements); etc. In the claims, as well as in the specification above, all transitional phrases such as “comprising,” “including,” “carrying,” “having,” “containing,” “involving,” “holding,” and the like are to be understood to be open-ended, i.e., to mean including but not limited to. Only the transitional phrases “consisting of’ and “consisting essentially of’ shall be closed or semi-closed transitional phrases, respectively, as set forth in the United States Patent Office Manual of Patent Examining Procedures, Section 2111.03. Use of ordinal terms such as “first,” “second,” “third,” etc., in the claims to modify a claim element does not by itself connote any priority, precedence, or order of one claim element over another or the temporal order in which acts of a method are performed, but are used merely as labels to distinguish one claim element having a certain name from another element having a same name (but for use of the ordinal term) to distinguish the claim elements. The invention also consists in any individual features described or implicit herein or shown or implicit in the drawings or any combination of any such features or any generalisation of any such features or combination.
