I was rear-ended a couple of decades ago while riding my mother's old 5-speed. I've been run off of the road by motorists and have had motorists get angry because they think I should be riding on the sidewalk or in what they think of as being a bike lane.

Of the last two one used his car in a threatening manner. Every time I crossed an intersection he would turn his car like he was going to run into me. The second one actually got out of his car and wanted to fight. In that case I was again on the sidewalk in an effort to put as much space as possible between the motorist and myself.

In both cases I kept traveling to an area where there were (hopefully) plenty of witnesses, in case I needed them.
