Let me know if you are aware of ANYBODY who has ever paid for an insurance rider for his personally owned car or truck for damage incurred while participating in racing events. Or ever been covered for such damage. SCUBA insurance does not count.

I've bought track day insurance for High Performance Driver Education, i.e. track days. there's a regular market for it, given that regular auto insurance excludes any loss on a track.
First time I did it, it was $400 for 2 days coverage for $110,000 property damage coverage. As for self insuring, which I'm a big advocate of, I could stroke a check for a $100,000 total loss but I wouldn't be very happy about it.
Since then, as the car has gotten older, and I'm more sure I can mitigate my own risk with a little prudence, I skip the insurance, essentially self insuring for about $60,000
