A 3-car smash which I just managed to catch as I drove by. I couldn't really see what happened at the time as I was focusing on the road (safety first - always) and just fired my camera randomly through the windscreen.

It looks like the BMW was at fault. It hit the silver van first, bounced off, losing a wheel in the process - which is lying behind it in the road, before burying itself in the front of a white van (which you can't really see in this view).
