Short version - guy with GT3 hands keys to friend. Friend mistakenly hits clutch instead of brake. Chaos ensues as GT3 hits Celica(owned by the 'safety steward' who set up the course), and then hits the Subaru which hit the Audi.
1. I would kill my friend for cracking up my GT3
2. How do you think insurance covers something that happens at SCCA
The Audi and Subaru were not even competing in the event, they were spectators. I haven't been to an SCCA event yet, but when/if I do - I'm gonna make sure I park a stones throw from the course.
