Trailer When plain old driving isn't enough, unleash your fury and climb to your car's roof for some fresh air... And hijack a ride from another car while you're at it! Gain nitro boost by jumping onto other cars, driving into oncoming traffic, and a variety of other crazy stunts. Only thing you can't do is brake! But why would you want to do that? Reach the finish line and you may unlock a bonus car or two!
