I spotted a following thing on the Carlswood, when I turned the steering wheel: There is also a very weird bug, when you hit wall or X-tree from the thin side: your car sometimes gets stuck, flies few meters away or it is thrown hundred meters high. It may also drive through it. Some of you may say, that I have nothing better to do than hitting the walls, but I think that such bug shouldn't occur on the track, which comes with the game. Actually, I discovered it because I was driving to fast on turn 2. I think it happens, because the thin side of X-trees and walls is 1 vertex thick (so it actually has no thickness). Perhaps making them thick would help.
