could fix the throttle with tape, that is not the problem. he'd have problems with starts- ie he'd stall out all the time.
quadruple amputeee = no hands how would he steer? how much of the arms does he have left, if he has to just beyond the elbow (has elbow) it shouldn't be too hard to hook up something. but if he is missing most of the arm. it'd probably be a bit too hard for the wiiwheel....
