I'd like to recommend everybody read a book called "Drive To Survive" by Curt Rich.
It's short, and it's an easy read. But it gives you a lot of tips about defensive driving, always knowing about your surroundings, etc.
It also teaches you some crazier stuff like 180 degree foward & backward spins, how to properly ram a car, and the like (only to be used in true emergency situations like when your life is in danger.....although doing a bootlegger's hairpin in a parking lot is fun

)
Best of all it's only like $15.
