I did the horn trick at a Mustang vs Grand National event back when I had a Mustang. I was 1/2 second slower than the Grand National I had to run and I had to do something as this was heads up and ford was way behind. We staged and I threw the old Stang on the rev limiter and layed into the horn and since both cars weren't all that loud it worked. I got a massive holeshot but he pulled my headlights out about the mph lights. My smile and wave back in the pits was met with a grumpy stare.....one point for buick.

I think part of the problem was when that run was made it was about 4am from what I understand.
