It's time to reach the exit. Things are getting deadly and it's just too risky to be out for too long. Also, there are many levels where you have to find the key to open the darned gate. There is nothing worse than being in a hurry, only to find that you're locked in. If you are wanting to perform stunts and jump, etc. you will hit the shift key to do so. Maneuver your vehicle with the up, down, left, and right arrow keys. As stated before, use your shift key for various maneuvers as well. To do a 180 and go the other way, hit the space bar. There isn't much time, so you'll need to hurry.
