I had a double commute because one of my customers needed help after my day job.

On the way there, for the first time, a motorist passing from behind in the next lane over yelled something rude at me, "Get on the sidewalk, dumb***!"
At the time it was a four lane road, 30mph speed limit, few cars and I was within 2 feet of the right curb going 18mph.
I did not acknowledge him.
