Some drivers think they are by once you are behind where they sit. He crowded but the road narrowed at the bridge. Possible he was just oblivious. Still sucks but we have to avoid the accident if we can. I have had my share of this sort of thing.
I watched it through. Not pretty by any means, but ought be "required reading" for bicyclist (and motor vehicle) drivers ed. Amazing how fast a rider can go from vertical in one line to horizontal in another. I was surprised, even if I shouldn`t have been.
