I think the idea of rewind is one of the best features added to racing games, but I have to turn it off because I can NEVER get it to work well enough to recover. It's always a problem with speed, and I can never pull back far enough to take care of it. Also, it helps that I can't friggin tell when I can rewind or can't so when I really screw up and it won't let me rewind, that's so annoying that I just said 'fuck this'
