A similiar thing happened to me the other day enroute to work, but this was mostly my fault. After going over an overpass and through a light I pulled up on the right side of a panel van. The van proceeded to turn to the right into a gas station, right in front of me.
Should he have checked his mirrors before turning? Maybe. Since he was in the right lane, I caught up with him vice him passing me, and there was nowhere for anybody to enter the road, he had no reason to believe anybody was there and really had no reason to check. But I should have known he would, or at least could, turn in front of me.
I wasn't hurt, I didn't even fall. But I did lean against the van as it turned.
This is the second time this has happened to me. The first one was the drivers fault and I came very close to getting hurt bad.
I guess the bottom line to all this rambling is that I just assume that every car I see doesn't me, doesn't care that I'm there, is more involved in something other than driving and I plan escape routes as I go along.
I hope everything works out for you. I would press to have the insurance pay for your repairs too. Take the bike to your LBS and have them check it over, cracks are sometimes hard to spot.
