Like H20HYBRID_GT said, that would be the best solution. 👍
What irks me most about the rewind feature in Forza 3 is that there is no limit to how many times you can use it, no matter what your selected difficulty level is. After all, you can customise all the other driving aids in that game, so why not rewind?

And the fact that using it doesn't lower your monetary earnings from the race. 👎 Something tells me that T10 didn't really think that feature through, unfortunately. I hope PD is a little more careful in implementing that feature.
