A friend of mine reported this morning on his experience with this challenge and said much the same as Duke
and others - that this challenge is very difficult indeed with the wheel. I don't use a wheel and I found this challenge pretty straightforward (3rd place on my first clean lap, and 1st after about 10 more tries). I'm leaning toward the hypothesis that using the controller is the path of least resistance here. Either way, it is a pity to hear from people like my friend (non-GT players and potential converts) that this challenge feels so unrealistic and can be prohibitively difficult, esp. for newcomers to the game, as I feel it is giving a misleading impression of what the rest of the game is like. That said, with so many experienced players (and actual drivers too) saying much the same thing, it is a little disturbing - and it is probably of little consolation to be faced with the idea of resorting to using a DS3 for certain missions...
