I tried this out recently and it's so obscenely hard that nothing else comes even remotely close. I have begun to think that the controller is just unusable with the game though and maybe that is my issue because when I watch people do it with a wheel they seem able to turn their wheel back and forth much easier without turning too much which is almost unavoidable with a controller. When I do a race it's like I'm driving on ice that makes every move hyper exaggerated but people with wheels don't seem to have any such issue.
Either way it's the hardest shit you will ever attempt and I think it's strange no one ever ranks it as such.
