A system for preventing driving skill atrophy comprises a trainer module that determines the driver's current skill level, disables certain automated features based on the determined skill level, and forces the driver to use and hone her driving skills. The system collects data to determine through on-board vehicle sensors how a driver is driving the vehicle. The system then compares the driver's current driving skills with the driver's historical driving skills or the general population's driving skills. Based on the comparison, the system determines whether the driver's skill level is stagnant, improving or deteriorating. If the skill level is improving, for example, the system disables certain automated driving features to give driver more control of the vehicle.
