Just a quick tip - take it FWIW. If you were helmeted and the helmet sustained the least little contact with any solid object - including pavement, make sure to claim it on the insurance claim. Helmets, once they have made contact, have done their job and should be disposed of. They are not intended to protect multiple blows. The insurance company WILL allow the helmet claim, especially if there is external signs of contact with solid objects. They will pay for a new one - but will insist on taking possession of and destroying the old one.
You probably knew this already, but what good is having a lawyer on this site if he can't spout off now and again!
