I think you have to keep the human factor in mind, someone has to let go of the button with the boxes and the no box racer has to let go of the button. The foot brake racers has to decide when on flooring the gas pedal and letting off of the brake pedal. It wouldn't suprise me that a good racer can win in either type of car, box, no box with a trans brake and lastly foot braking only Some of us will use any excuse we can to not figure out how to win constentintly
