I was driving around in the XFR and when in was rolling on to the roof again the wheel on the ground went trough the track and I got stuck. Replay attatched it happens on the first corner after the second split. Really weird, dont know if its about the car, track or is it the physics. And if you watch that replay you might want to mute your sound because that tire makes a really bad noise.

I cant watch it because i'm at work at the moment, but this sort of thing can happen in games where you've confused the collision detection system, and it's usually the result of a momentary computer-pause because of a background task or a low framerate.

Whoah thats really wierd... It looks like the wheel actually bent up into the chassis and just locked up the car instantly. Also the roll cage comes through the roof
