Discription of Events: Pulled in front of me with only 1 car space in fast lane and almost caused a multiple car and big rig accident. He then slammed on breaks. I then took picture of car to report him which made him extremely mad. Tried to get me to pull over several times by pulling up to passenger side of my vehical and aggressively followed me for 2 miles while I tried to exit offramps. Tried to lose him but kept following me until finally lost him. Felt if he had stopped me I would have been shot by his actions. Tried to get away from him but he would not stop following me.
