Shoot into the air
At the end of pit road at Las Vegas Motor Speedway are three asphalt lanes that go right to the infield wall. Hit the middle lane directly in the center of it, your car will sink into the ground, then get shot up in the air doing flips. Note: You must be driving faster than 90 mph.

Ghost car
Select the Las Vegas Motor Speedway. Come off pit road and follow the inside road and two roads down. At the second road, turn left and drive slowly (under 90 mph). You will fall into nothing, appear back on the course as a ghost, and slowly change back to your original appearance.
