You do realize the difference between physics and bugs, right?
Nice way to make you look like a total troll, by the way. I enjoy people who don't have GT5 come here to say how the game that hasn't been released yet is better than the one that has been released, has been reviewed with impressive results, and is being greatly enjoyed.
Actually, aside from the part where it sticks into the ground, that was actually a pretty realistic crash.
And respect here... from a GT "fanboy" for the fact that you can actually flip a car over a curb (looks at GT... says... "if you really loved me, you'd do this for me!" )
