Holy cow, sounds terrible. But to be fair to the driver, it just sounds like one of those accidents. We all know, if we drive cars, that sometimes things and people just come out of your blind spot and no matter how careful or vigilant you are, it just happens. Lucky you weren't hurt worse, but that sucks about the bike.

Your friend thinking the rider was dead reminds me of a photo I saw, of Laurent Jalabert's bike after he had that horrible crash in the Tour in 1994. The front of the bike is basically just broken and folded over, the bike is in two pieces. He just went right over and landed on his face. As we all know he didn't die but if you'd looked at his bike, you'd for sure thought he was dead!

Rest up and take care of your injuries! YOu may want to go for physio because you'll have a lot of aches and pains coming out of you. I was nailed by a car last fall and got off with a broken bone in my hand, but it was landing on my back that caused the most problems. It hurt for weeks after.
