When a driver makes a turn in a race, the ideal situation is that they should do their final deceleration into the turn, and do their acceleration out of the turn. There are two primary problems with this ideal. The first is that letting up on the throttle causes the front end to rise, and pressing on the gas causes it to rise some more - causing a double-transition that results in two somewhat unpredictable decreases in the amount of front-end traction. The other is that this often necessitates a downshift, which itself can cause issues with loss of traction.
As you may or may not know, I live on Cobb Mountain in Lake County, California. This is a really beautiful piece of country, and many parts of it enjoy microclimates - almost nanoclimates, really - that really mitigate the impact of weather. Unfortunately, my particular portion of the hill isn't in one of these areas and we get the worst of all worlds; hot in the summer, where people just around the corner from us are ten degrees warmer, and cold in the winter, although that's an affliction shared by pretty much the whole hill. Clear Lake is at about 1000 feet, and we're at about 2700 with only one significant mountain range between us and the coast (since we're on top of the second one.)
