This man stomped on his brakes several times while going below the speed limit in the left lane. Once he got to the middle lane, I began to pass him on the left and he tried to run me off the road. He then started flipping me off, & when I tried to get to my exit lane, he wouldn't let me go to the lane. He actually drove next to me and came to a complete stop on the highway so that I couldn't get to the right.
