I have. It's frightening. I was sitting at a light one day waiting for the cars on the other side to turn. I was turning left. The car behind me was honking at me and as I started to turn, he sped up and zoomed around me and turned. I beeped at him and kept going. As I got to the next intersection, he stopped his car, got out of his car and starts yelling at me. I had my then 6 month old in the car with me. I was seriously worried he was going to pull out a gun, he was out of control.
