Discription of Events: Police were on the left side of the highway so all the traffic including myself yielded to the right lane. After getting past the police I turned my left blinker on to reenter the left lane. At the moment I was entering the left lane with more than adequate room to do so, this guy and his wife in a Lincoln navigator accelerated to cut me off from getting into the left lane and flipped me off as they passed me. I raised my arms up to on a "what gives" motion. He then unrolled his window to tell me he was going to slash my tires. It is sad people exist like that in this world.
