Discription of Events: This occurred on 95 south. I first noticed the driver tailgating others and slamming his brakes. He was already angry and passed me on the right in stop and go traffic then slammed on his brakes trying to get me to rear end him. When I backed off and switched lanes to avoid him he would switch lanes and slam the brakes again. Later he caught up to me and prior to exiting at eta 495 he rolled down his window and I could hear him calling me a stupid, fat bitch.
