I had a similar bizarre reaction once. Some nutball in a 90s Olds fwd whatever was doing some REALLY crazy dangerous stuff to keep me from getting around anyone in any lane. I know that I didn't do anything to them before hand because I came up behind them as they were toodling along. I stayed a bit relaxed and hung back when I realized they were nuts. When I relaxed, they did to. I waited it out about 2-3 miles. Then I saw a large opening not only to get around in front of them but to put some distance between us and took it. They didn't seem to like that, but there wasn't anything that they could do about it and I was long gone.

Some people are just nuts. Don't try to figure out someone that's irrational. You won't.
