Discription of Events: VIN #: WAUPPBFF3HA13170 The driver kept steppping on his breaks in front of me literally fully stopping in the middle of the freeway car pool lane. I never tailgated him to instigate this. He did this over 7 times, then drive to the side of me and tried ramping into me to force me to hit the guardrails. Thank goodness I kept study and kept watching him wave back and forth away and toward my car to scare me to crash my car. Then drove behind my car and literary tailgated me so so close that had I stepped a second on the break he would have hit me off the road. He kept speeding up to get me to go faster and faster. My dash cam has most of the incident recorded and I have turned it all to the authorities to file a misdemeanor. I was not hurt and feel very lucky.
