Extremely High speed precision driving is possible Only because of footwork. Walter is just UnFrickenBelievable: Left foot braking. Heel and Toeing. And playing the Throttle to both catch slides And create them to--rotate the car into the corners.
Driving is both Science and Art. I doubt if "they" have any clue about this fact. I really do.
* Note: I'm the OP btw. And yes I understand Walter's footwork.
