In the motor vehicle with an automatic gear-box of the parent Application comprising a system for over-riding the operating elements 103, 104, 105 such as for fuel supply, braking and steering at the main driving position from a second driving position and wherein each operating element at the main driving position is operatively connected to a servo-control device 200, 300, 400, the devices being operatively connected to a controller 500 at a second driving position, each of the servo-devices comprises an oil delivery pump 210 driven by a reversible electric motor and connected by two conduits 211, 212 to an hydraulic motor 201 containing a piston 202, a connecting conduit 213 being arranged between the conduits 211 and 212 containing an electromagnetically operated valve 230 which blocks the conduit 213 when the electromagnet is energized. When the operating elements are controlled from the main driving position the valves 230 are open, permitting the pistons 202, which are connected to the elements, to move freely. When the switch 501 on the controller handle 505 is closed, the valves associated with the pedals 103, 104 are closed and the valve associated with the steering element 105 is closed until the handle is rotated to energize the steering motor 220. The devices 200, 300 are actuated by movement of the handle 505 towards or backwards respectively from the neutral position.
