Ok, hold up. I've seen drivers stop, turn around, and go again on a qualifying run, when they haven't taken the green flag yet. But KB did take the green, and was coming to the white flag, stopped, and took a "re-do" on his second qualifying lap. Or I guess it would still be his first, since he didn't actually complete the first one. I guess it's legal, but it doesn't seem like it should be. Doesn't matter in this particular case, since he wadded up his car on that second lap.
