I haven't been to many shows this year but I didn't realize it was such a problem. I'm usually at the drag strip and have never seen anyone leaning on someone else's racecar.
At the drag strip the cars are in the pits.. I believe the racers are usually to busy with their cars to bother nitpicking others.. Their kids and families usually are busy acting as pit crew, and bystanders walking the pit areas usually seem to just look and not enter individual pit stalls (for the most part) I believe this helps keep these incidents to a minimum at the track
