Abstract
A toy vehicle and toy vehicle game are disclosed in which a plurality of controllable toy vehicles collect current from conductor strips in a slotless track and switch lanes when current polarity is reversed. A toy drone car is used in the game which collects current from the strips associated with the other cars and it includes an electrical circuit which insures that current of only a predetermined desired polarity is supplied to the motor in the vehicle to propel the vehicle in a forward direction around the track. As a result, the vehicle is driven about the track in a forward direction regardless of the polarity of current applied to the collector strips. In addition, the drone car includes an automatic steering system which causes the drone car to continuously switch lanes in an apparently random alternating manner as it moves along the track.
