Some people simply like to upset others.
In California I used to leave in spot, where double lines on 45 mph highway merged into single 30 mph lane.
The highway was used as baypass for packed freeways, so lot of afternoon traffic.
The merging lines were pretty long and with stop @go traffic it was situation like OP had. Still when the dual lanes ended and become single lane, somebody always wanted to pass you.
I had situation when towing equipment hauler behind F250 - a lady in Honda tried to force my 5000 lb frame trailer off the road.
Than when I call the police, she made up the story that I cut her off.
I was in the truck cabin 40 feet in front of her.
The best best part - the highway become rural, no-passing highway for next 9 miles, so even if you got ahead of 1 car, you still could not pass the hundreds that were already there.
Can't fix stupid.
