Some people may disagree with me, but there is a big difference between AutoX and driving a road course. Smoothness is a bigger factor on road course at 120+mph than it is in a parking lot at 60mph or less.
Some people do learn faster than others, and some people start out a little further ahead of others, I was just generalizing that most novice drivers slow their cars too much for a turn. Braking, typically, is a digital input. You are either on them or not. It is not uncommon for a new driver to slowly apply the brakes before a turn, this builds up heat without slowing the car a great deal. This can cause the brakes to wear much faster.
