Discription of Events: Merging on highway, cuts through by driving outside of lanes *unfortunately I saw him again* Sudden switching of lanes without signaling, causing me to stomp on breaks (he was trying to beat cars as much as he could) When green light came, he went back to the lane he originally came from during an intersection) Another merging of lanes and drove me off the road since I had to be the one merging and he was not letting me in (he tailgated the car in front of me)
