What? I never hit him!
The bike makes cars crash if they get within about a half of an inch to the front of the bike. The physics are all sorts of whack, not to mention there's no cars driving the right direction... the crashing cars should be slowing down, but the bike is still supposedly moving, so they should still pass off the screen pretty quickly. Also, maybe you should have the biker bail if he hits a car? Seems pretty logical.
Good idea, needs better execution. Plus, i don't like the song. bleagh. Pop punk sucks.
