I was merging into the express/fastrak lane where the highway split off into a new lane. The white car came out of nowhere behind me speeding and came very close to hitting my car. I was forced to go 100mph to avoid collision and even THEN the car still did not ease off my tail. In the end I had to switch back into the lane on the left to let it past me. I then saw the same car tailgate 2 other cars. Driver was a bully.
