actually, I'll have to side with Kalfireth. The physics on NFS are rather stupid. I have High Stakes for PS1, and when you hit a police interceptor, your car flips in the air? I don't think so. if you hit one of those, your car is going to flip through the air, total the interceptor, and kill you in the process. At the very least they should end the race right there. Or make the physics enough to where you hit an interceptor going 60 mph while you're doing 120 mph, the cars should bounce off of each other and hit walls and all kinds of things ... rather annoying that the physics is wrong.
There is one cure for this. A cheat code. On the PS1 version, hold down d-pad up, square, and circle, and your car becomes heavier. The physics are more realistic that way....
