Sorry to hear about your friend Dave.
I had a motorbike vs car incident a while back, basically T boned a car at 40 mph and went sailing over the bonnet. Got some serious air time plus a good slide down the road, it happened outside a hospital so that was pretty convenient. The first person that came to help was a priest, he said " I'm a priest but I don't think you really need a priest today" or something similar. So lucky all I had was a sprained ankle, plus it was technically my fault (speeding) but the car ended up being stolen and kept going so then by default they became the at fault party.
