That reminds me of an incident a few years back. Just outside Duncannon US 15 South goes from two lanes to one for a very short stretch between the exit and entrance ramps from the town.
It was me and one other car for about two miles, I was in the lane that kept going, he was in the lane that exited, and we were side by side. At the absolute last minute he makes it clear he is not going to Duncannon, not exiting the highway, and not going to accept being behind me. I had no good reason to slow down and let him over since I couldn't even see his turn signals because of where I was. So he just started coming over into my lane and almost forced me into the barrier. I figured it out when my wife yelled.
That jack-off was lucky I didn't torch his car. It was a black Jeep Compass with a very distinct plate number, from the town I worked in, and I knew where he lived.
