Well, quite. But as IGN pointed out, that's not in itself a bad thing :
At the end of the day, you're the one in control of the rewind function. Don't like it? Don't use it.
The great thing about Forza 3 is that it encourages even the novice to take off the training wheels and drive freely with the assists off. A rewind function allows you to instantly skip backwards in five-second intervals during a race. Misjudge your speed on a tight corner? Rewind. Get tapped from behind and spin out? Rewind. Your cat jumps on your face causing you to crash into a wall? Rewind. There's no penalty for using the rewind and no limit. Some might call this a "win" button, but I think the rewind is a crucial addition to Forza 3. It can become a crutch at times, but it also frees you to kick the difficulty up to a higher level and get a true appreciation for your car.
