Vehicle guidance and control systems that use the intensity of a field radiated from a source of radiation to define the track or lane for operation of the vehicles. The source of radiation used is a single source of radiation in the sense that vehicle position relative to the source of radiation is sensed by sensing intensity of the radiation at the vehicle, rather than the difference in field intensity sensed from two physically separated sources of radiation. Exemplary embodiments using a single magnetic field for navigational control are described, including a basic system for a single vehicle, a tethered system having steering and speed controls for creating a multiple vehicle racing environment, and a radio controlled system, also for creating a multiple vehicle racing environment and in the embodiment disclosed, also useable as a stand alone RC controlled vehicle.
