Using Vehicles Wisely
When selecting a vehicle you need to look at the lower bottom of your screen. You will see a small picture that says POWER or SPEED. If the picture says POWER your vehicle is better for climbing hills. If it says SPEED then your vehicle is better for cruising. When you use the MONSTER TRUCK all four wheels turn so when you miss a CHECKPOINT hit the brakes and turn in any direction you choose and you will be facing the checkpoint giving you the opportunity to get the checkpoint and repeat the turn. If you use the DODGE T-REX its better for climbing. Its top speed is not bad for a POWER vehicle.

Flips and Tricks
This might not be a cheat or hint but it's pretty cool. when you go off a high ramp or cliff, with a Pro or Unlimited car you can do flips and tricks by rotating the right thumb stick.
P.S. on the moon with the unlimited Chevy blazer is the best car to do flips and tricks with

Hit Helicopter
In every level a helicopter is flying around, but in Hawaii, you can hit it!
What you do is in Hawaii go to the top of the volcano where there is a ramp in the grass coming from a mud road, follow the road to get to a radio mast, at that radio mast there should be a car park, push the car that has it's back to the volcano, forward until it is off the car park ground, then climb on the vehicle, this works best with Hummer© because it is chunky and good climbing, when the helicopter passes it will be very low and hit you, then go through you

Go Faster Than Top Speed
This works best on very steep hills i.e. in Yosemite, with your vehicle in free roam, select manual gears, and when you get to the top of the hill, get near the edge in gear 1, accelerate VERY little then change to neutral, your car will roll down the edge and if you accelerate in neutral you shall go higher then top speed. For instance: my favorite car; the Hummer© soft top, its top speed is 113 mph, in neutral I reached 155mph, if I went on a longer hill i might break the 200 mph marker.
