A system that evaluates driver’s aptitude and shuts down the vehicle when incompetence is detected. Technology exists that measures a driver’s fitness and issues warnings when a driver is judged overly tired or impaired. The system remembers a driver’s normal behavior behind the wheel and establishes it as the driver’s baseline profile. Continually measuring factors such as speed, lateral acceleration, steering wheel angle, pedal use and so forth, the system determines if there is any deviation from the baseline. If so, it alerts the driver visually and audibly that it’s break time. Even external influences such as crosswind and road surface are factored in.
