I've uploaded a new version, with new graphics, and simplified code.

The scrolling issue is still there, but it's not as bad. It's a little smoother now that I moved the wheels aswell, as opposed to letting them reset to the right position automatically.
It seems like the physics interferes with the move, is it possible to disable the physics when you hit the edge, then enable them again?
Strange thing is, it worked great when it was just a ball. As soon as switched to the car it went bung.
