I watched the Skip Barber video last night and saw a lot of things that I do wrong and the reasons why I suck so bad. But I want to make sure I'm not misunderstanding a couple of things. #1. The gearbox is not for slowing down; the brakes are for slowing down. When approaching a corner, you downshift not to scrub off speed but to get to the gear you will need to be in when you exit the corner to give you the maximum acceleration. #2. A racecar should be either accelerating or braking. "Freewheeling" by simply letting off the accelerator sacrifices rpms needed for accelerating and also could potentially result in a skid if done suddenly at high speed. Now, I know the things above aren't true all of the time, but are they generally true? If so, they really change the way I look at driving on a track.
