Car preview:
Hold L1 + R1 when purchasing a car or selecting one out of your garage to use the D-pad to move it in any direction.

Stay on track:
When you are going around a sharp corner at high speeds, you will often go off of the track and lose speed and risk of losing your place in the race. To prevent this, simply let off the gas completely at the middle of the corner until you start to skid. Do not panic. When you start to skid, accelerate again and you should regain control. Straighten yourself out and you can get to your top speed faster than if maintained the same speed throughout the entire turn.
