Not me, but a guy I know, hit by a car at the weekend - up onto the bonnet, but fortunately just a few bumps and grazes. Bike looks like having a knackered form and brake at the least. Police attended, agreed driver was at fault. Driver currently helpful and wants to pay for damage to bike. Started to feel stiff in neck and upper arms the day after. Asked for advice on next steps. My advice was:
1. Contact your GP and get properly checked over (he's doing this)
2. Make sure you get the police incident number.
3. Possibly contact one of the cycle specific lawyers (don't think he's a CTC member) in case the driver baulks at damage payment later on.
Have just thought of '4' to go to the local bike shop and get the bike checked over and have the repairs priced properly. Anything else? (I offered to contact a cycling hive-mind on what to do and he's happy with me doing that).
