The Peddle is only used for backing up, driver leaves off hand brake and I set the high idle just before he pulls into the beams. Saves having to deal with a battery. Its a good thing to have if you are running a battery transbrake. Seen wires and terminals come off, batterys go dead or not charged enuff to hold. One can always step on the peddle and swap feet if they have to. My driver as it stands can jump into any fuel car and drive it without having to change routeen, or I can get a cellebrity fuel driver in there to make a pass with minimal instruction. The other side benifit is that the entire driveline is loaded for the launch. transbrake only locks the trans, but couplers,driveshafts, R&P, and axle splines, float and impact when the button is released
