at a divisional race in Maple Grove in 2007, the guy next to me and I were warming our cars up and testing our trans brakes. I always did this on jackstands, just in case...he had all 4 on the ground...track security came by and booted him out of the event and I think he was suspended for a couple of races.
Anyway, there are two ways of doing things during a sanctioned event and then there is just pure logic...
