In practically every racing game I know there is some way that makes your car accelerate faster and/or spin out less when the lights turn green at the start. Be it watching the fingers of a character floating on a cloud (Mario Kart :-P) or having the RPM in the yellow zone etc.
Yet somehow, even after beating all the world tours and X-Games, I still haven't figured out how not to be in last position just after a start in DiRT 2. That I don't drive a car in real live does not help either.
So: How do I get the best acceleration at the beginning of a race a) in DiRT 2 b) in most realistic racing games.
