Multi-car trackless transportation system

The multi-car trackless transportation system includes a pilot car and at least one secondary car connected to one another in a manner similar to a conventional tram system or the like. Each of the cars is connected to adjacent cars by pivotal connectors. The pilot car and the at least one secondary car each include an individual motor, drive system and steering system. In order to develop a virtual tramway or path, the pilot car transmits instantaneous velocity and steering angles measurements to the secondary car. The secondary car then applies these signals so that it has an equivalent velocity and steering angle at the same location as the pilot car when the measurements were taken.
