Some time ago i shared my encounter with a ranting rage-filled driver here on BF.
He cut me off and I fell trying to stop without striking his car. He jumped out of his car, still calling me names, and came towards me and I pepper sprayed him thoroughly and called 911. I had a couple of witnesses and, it turns out, he had a serious warrant related to some sort of violence.
He went away in a black and white and I just went on my way.
A man once yelled: "Get on the sidewalk" as we were stopped at a light. I asked, "Are you joking? It's against the law." He repeated, louder: "Get on the sidewalk!" I said: "Oh! I see, you aren't joking -- you're just stupid!"
