A dual-vehicle operating system permits the simultaneous operation of two automobiles at one time under substantially identical conditions by a single operator. The system has a lead vehicle, with a driver, a servo operated driverless trailing vehicle, and a zero-force mechanical connecting link. An electronic control 'drives' the trailing vehicle through servo controls which operate the throttle pedal, brake pedal and steering system of the trailing vehicle. The zero-force link contains transducers which provide lead vehicle responsive inputs to the electronic control so that the trailing vehicle mimics the lead vehicle. Both a manual and an automatic override of the electronic control are present to convert the zero-force link to a mechanical towing system.
