Good luck finding ANY insurance company that will cover Open Track time. I got dropped from State Farm just for having a preppared vehicle.
Sounds like that crash was due to a pace car that failed to gather the field properly follwed by an improper display of the correct flags. Guess you had to be there but then again I'm glad I didn't have to witness it.
Drag racing may not have multi car crashes but it's only fun for the racer...as a spectator, boring as hell. I'll take three hours of ALMS any day. Biased road race fan point of view.
