For the reason of the braking requirements I found a second hand A frame with over-run braking. It works on the tow hitch just as a trailer with over-run brakes would, this then operates a cable. You run the cable through the partially opened driver's window, put a frame between the driver's seat and brake pedal, when the over-run is activated it presses the pedal. Better than a trailer in some circumstances, not as good in others.

Yeah still not 100% as a car brakes need the servo to get full effect. it really is almost impossible to make an aframe towed car fully legal as a trailer. and you insurance will jump on this in the event of you're been involved in an accident.
