"+1 Ian" (maybe I should make that my sig). btw, how is it possible to not know what direction your wheels are pointed unless the car is at a complete standstill or the wheels are locked anyway? You have a steering wheel... you just turned it... in fact, FF is trying to re-center it. And, well, if you honestly still don't know, you should know how the car's moving and what steering inputs should be executed for whatever your desired outcome.
Besides, there's a steering position indicator already built into LFS for mouse users with the wheel turned off using the cockpit view or chase cam or something... or you?
