I posted one a while ago...
I was cruising down a bike lane.
The car behind me slowed down to make a right turn, I think, and made the turn.
The car behind that one also slowed down.
And the third car didn't.... CRASH
With the first car having made the turn, and the next two still moving forward down the road towards me, I made a quick exit onto the sidewalk.
I think I've had a similar accident happen while driving my Fiat. Stop light turned green. Cars moved across the intersection, but then for some reason stopped, and I heard a CRUNCH behind me. I hit the gas and moved as far forward as I could to try to make my already small car as small as it could be without out the rear end being accordioned.
