At start of game go to the options menu. Then select 
practice. When you get there first get the guy with 
the gun out of your way because he might mess you up. 
After he's dead pick up the car and fly through all 
the rings even through the last one, you can't simply 
walk through it. If you successfully did this there 
will be a glitch in the game and you will be in the 
car.
