I've noticed that in Forza replays when I didn't notice it while driving. I'm not sure if somehow the effect is dampened when you're in the moment, but I've had races that felt perfectly normal, then I watch a replay and I look like I'm jerking the wheel to lock and then back to center over and over and over around every corner.
Then again, I've always found it difficult to drive with a controller, even since GT1.
