Just replying to say if you are a Costco member check out their insurance. It is half what other providers I've checked out for us (State Farm, Allstate, Travelers, Cincinnati, Progressive, Hartford [via AARP]).
This is for two cars (wife and I are both over 50 now) that have 500/250 coverage...
Absolutely Lewis' fault. He was the only driver with room to give and should have for obvious reasons (first lap, team driver, dust on the track, etc).
He knows it, the drivers know it, the world knows it.
I'll admit when no other car is around me I don't bother to signal...don't see the point.
Kind of like people that signal leaving their driveway...always makes me shake my head.
