Discription of Events: This lady was driving right up on me from behind. We were taking off from a red light and I was up to about 45 in a 50, not quite there yet, and she was so close I could barely see her headlights. Then she flashes them at me and swerves it into the next lane to go around me. No blinker, no signal, nothing. Then she speeds up to probably 60 and is boxed in behind two cars in each lane. So she rides the line until one of them turns and does the same thing. I drew the line and called the cops when she sped into an intersection when it turned red and then stopped and waited for all traffic to cease. Then she took off down a residential street.
