Driver doing a burnout with cars staging ahead of him is an idiot. Crewman giving him the OK is an idiot. Where's the water box & starting line staff, who are usually making sure that kind of stupidity isn't allowed to happen?
I'm surprised the guy in the Mustang didn't get out and go after the moron; the guy deserved a beat-down, especially after loading up & leaving like weasels. I wouldn't be too happy with the starting-line guys, either.
