People spend so much time trying to prove or disprove these racing sims are realistic based on assumptions of assumptions.
It so strange, people want to tell if a game is realistic so they compair it to some other game, or what inputs can be used.
A steering wheel in most cases is simply moving your rack back and forth, why couldn't you move anything back and forth to represent that? it may be strange and take getting used to...but that doesn't make a game unrealistic...Hell some monster trucks have their rear steering operated by levers...
Has no one driven a car before? does it feel like that? You don't have to own a F1 car, or have sponsors to go racing. Find your local club(just because they don't advertise in the sunday paper doesn't mean its not there) and go auto cross. Does the game feel like that?
I will say LFS cars feel the most like my car (race springs, upgraded shocks, HLSD, sways, ect...), and that rFactor feels NOTHING like my car.
Ive never driven high down force open wheel car but I think rFactor does a better job of relating loss of grip/down force with higher slip angles...
