The vehicle convoying system of claim 17 wherein the first module comprises a first communication system in operative connection with the first processor and the second module comprises a second communication system to communicate with the first communication system in a wireless manner. 19. The vehicle convoying system of claim 18 wherein the second module comprises a second processor in communicative connection with the third sensor and with the second communication system. 20. The vehicle convoying system of claim 19 wherein the second module comprises a connection sensor in communicative connection with the second processor to sense when the tether is connected to the leading vehicle. 21. The vehicle convoying system of claim 20 wherein the extending end of the tether comprises a magnetic coupling. 22. The vehicle convoying system of claim 20 wherein the signal emulates a signal from a manual control system of the powered vehicle. 23. The vehicle convoying system of claim 22 wherein the manual control system is a joystick. 24. The vehicle convoying system of claim 1 wherein the signal from the convoying system to the controller is adapted to enable to the controller to control the drive mechanism to drive the powered vehicle to maintain substantially the same speed as the leading vehicle and substantially the same trajectory as the leading vehicle. 25.
