I was going to revive a 
thread from 2004 but decided to start anew...
They were kind enough to send me a full new policy when I added the STI rather than just amendments that have happened. If you read the 2004 thread, it was very strict about even being "at a track"
At least my Safeco policy has relaxed that exclusion. Here are my pertinent exclusions for 2006.

 The way I read this, Audi/HPDE/etc events which are not timed, non-competitive, and might even qualify you for discounts are covered.
Pretty much anything else that involves competition or even the future expectation of competition is not.
Again, that is my interpretation of my exclusions in my policy. I take no responsibility for you, your car, your policy, etc. etc... Your mileage may very.
Discuss....
