I was driving on the highway today and one of their drivers came up on me and kept blaring their horn. I exited off the interstate and he followed me, still honking. When I stopped at the light he got out of his car and screamed at me to get out of his way. Told me I was driving to slow. I had been doing the speed limit, in the far right lane. He followed me thru town and kept running up on my bumper. He has serious issues.
