Maybe he cut them off in traffic. I was making a perfectly legal right turn onto an Albuquerque boulevard one day and it conflicted with an illegal u-turn being made by the driver of a car full of gang bangers. I didn't yield to them which cut him off and forced him to hit the brakes and fall in behind my truck.
That really made them mad and they followed me several blocks taunting me to pull over. They even drove up into a parking lot parallel to the street to try and get ahead of me on the right side of me.
I hear you. See my post to “No Grey Areas’’. Thank God it didn’t work out different for you that day.
