Indestructible cars, moon physics, AND idiot AI: Is this the ultimate Gran Turismo 5 glitch?

Give it a click. You know it'll be worth it.

So the car spins out. Fine. Then it loses all body mass and launches into the air. Okaaay... And then it bounces undamaged off a couple of other cars and the trackside wall, before eventually coming to rest on top of another car without knocking its newfound steed off course by an inch. Seriously, Polyphony?

And then the car underneath gives Jimmy McBrokenphysics a lift halfway around the track, neither driver seeming particularly bothered, or even aware, of what's going on. Please excuse me for a few minutes. If you need me I'll be in the next room trying to surprise myself with a random drug test. You know, just to make sure I have actually seen this.

How are you getting on with GT5, if you've bought it? Seen anything as mad as this? Or is the monicker of The Real Driving Simulator holding true for you?
