Thanks, this works. It's a bit annoying, but I think I'll get used to it. I wonder if it's a bug in the game or the controller (haven't used it anywhere else yet).

In 90% of all races the wheels will steer completely left at the start until I start Input with my XBox 360 controller. It's not the keyboard interfering, I changed the key bindings to several different values. It only happens right at the start of a race or when I restart the race or reset to check...
