I had someone do that to me just the other day.
I was in the middle of the lane with the advance turn light and a clown in a SUV decided to go around me in the middle of the turn. I know he could see me as I have a Radbot 1000 on the back of my rack and it was turned on and he made eye contact with me as he went by.

I like to think he was a doctor and he did it to rush to the hospital to save a life, but it is more likely he was just a redneck JA that thought is would be OK to endanger my life to save 4 seconds on his commute home.
