This is stupid... because that 5% that DO use the feature are you hardcore race audience. They are the guys with the crazy steering wheel setups and the whole deal. THEY are the guys who will most likely buy the damn thing either way.
Yeah, I am sure they did the math and those 5% will most likely still buy the game for fun. And I doubt Codemasters is worried about their setup since I doubt they make money from that gear anyway.
