Abstract: An apparatus with a tire that is capable of castering 360 degrees replaces the rear wheels of a front wheel powered automotive vehicle to give drivers an educational experience that simulates the effects excessive speed has upon entry into curves and turns. The rear wheels can remain locked in a non-castering position, whereby the vehicle will perform in a conventional manner. However, under the control of an instructor, the lock can be removed to free the casters, causing the rear of the vehicle to move in the opposite direction from the steering input to simulate a rear wheel skid. When the vehicle on which the invention is mounted is being driven in a straight path the freely castering rear wheels will trial in a straight path. When there is a change in lateral position, such as that which occurs when entering a curve or making a turn, the rear castering wheels will continue to travel in a straight direction causing a lateral acceleration resulting in a rear yaw.
