Easy Money In Crash Mode:

When you are about to hit the car you think will make the biggest crash, use the turbo and drive towards that car. Hit your brakes and do a power slide into the car. This should put you into the air. Note: This will not work on trucks. Also for easy money in Crash Course 6, select a car that catches air easily (such as the SUV). Start with a boost and burn out of the tunnel. Go all the way to the left and hit that car.
