i dont know how the magazines do it but i have heard of a method in which there is a device that shoots down a mark on the pavement when brakes are applied then you just measure from it to the stopped car. i suppose that the magazines have some electronic device to do it now. road and track always had a bike wheel looking device that they attached to the rear bumper for measuring such things but probably now they use something completely electronic.

if you could stop faster with abs then race cars would have it. they dont. when they have lost it they just lock them up and slide. this also keeps them sliding straight and not into the wall.
