People are confusing

After work today, leaving the train station and toddling along my usual route, this car pulled up beside me and someone inside yelled, very loudly and distinctly, "You... are not... a car!"

He seemed upset about it.

My initial reactions ("That is why I am in the bike lane" and "Neither are you, you [adjective] [noun]") were sadly swamped by confusion until he was out of range. Not that I think it would be a good idea to get involved in a driver-bicyclist altercation of any sort, but some people really do need to be... educated.
