Hint: Tricks in mid-air:
When you approach a ramp, get enough speed up and once you have jumped off it, hold Triangle for a Powerdow. You can actually pull it off in midair and land it by releasing Triangle before you land. You can also do this with a Surfing Powerdown, but you have to release the trick button and Triangle to land it properly, or you will crash. You can also Powerdown onto a ramp and do a rotation trick on it. Note: You do not get any extra points for doing a trick in midair, just for the jump distance.

While turning, press R1. Wait until you are in front of a car and point the Left Analog-stick the opposite way that you are turning. You will keep turning, but at a slower rate. Note: Do not release R1 until you dodge the car(s).

Hint: Caught on camera speed:
On every level, there are cameras which will photograph your speed when you pass them. Sometimes you need a certain speed to obtain "Respect". To do this easily, obtain a "Powerband". Press R2 approximately 350 feet from the camera to Powerband past it with speeds in excess of 250 mph.
