dont ask how but i managed to get my car to hit into the fence just after the banking of turn one on the KY national reverse track. when i hit the fence my car stayed there, it was stuck.
see atached picture.

Yop, known problem

Also the inside wall of KY is quite....erm...bouncy
I hope this will be fixed with one of the next patches.

i was orderd to report it by the other racers lol
