It's so stupid the game doesn't give you an option for changing the keys , it's not even compatible with any Joystick but xbox's! isn't there any patch to fix that?
To be honest, I never thought racers were a very good genre to play on PC with mouse and keyboards only. Unless you could use a controller, or better yet, a force feedback wheel, the immersion is just not there. At this point a 360 controller is better anyway..
