After you start, simply turn around and start racing the other way. The other cars will
follow.

Bonus tracks:
Goto practice mode, select a track, car, and transmission. When the race begins, turn you
car around and drive in the opposite direction. When you pass the first check point, you
will be placed in first place. Then, the other cars will eventually turn and follow. Three
