I never said that. I said that if you can't use a wheel then either try a different game/controller, or don't expect LFS to give you help making you quick.
In real life if you wanted to drive a race car (I have no idea what disability you have - could be an ingrowing toenail or no legs at all, or anything in between) then you'd have to make serious modifications to be able to drive, or just not drive at all. Why should LFS be that much different. If you can't use pedals, then hand throttle/brakes are possible, if you can't steer then there is always vague support for mouse/keyboard (just don't expect them to be very good ways of controlling a car).
I find it insulting that a) you just use the disabled word, which is so meaningless and overused and b) you failed to read/understand what I'd written, or the meaning within.
