The extreme behavior, yes.
There's this guy that moved to my town, which is known for being chill. One two occasions I've seen him in action. The first time I was in a grocery store parking lot, and a car (not mine) was stopped in this area that is not a moving lane. The guy was hanging out out there waiting for someone, presumably for them to come out of the store. Anyway right next to that is the moving that, but this guy in a big as truck was stopped being the person who was waiting, and after a minute they started honking really loud. And no movement, the guy gets out. He had a crew cut and his face was bright red. He was screaming like a fool at the car in front of him, yelling "move you your fucking ass!!!. I don't think the guy who was stopped realize he was being yellowed yet, until the red-faced guy started pounding on their windows and kicking their door. I was like... dude... clearly, the moving lane is to the left so the guy didn't even need to be waiting behind him, he was in a loading zone. But the way was freaking out, pounding on the car, screaming obscenities. Finally the person realized and looked over their their closed window like... are you serious dude? They started to move but the guy started grabbing on the door handle, trying to open the car, screaming that they were needed to fight, "fuck you asshole, I'm gonna fuck you up!". I watch the guy who was being harrassed shake his head and look at me and keep driving, and the crazy guy literally ran after the car screaming obscenities, everyone else in the parking lot was like whoa, chill. He chased him about a block before he gave up and walked back to his car. That was the first I've seen of it.
Then like 6 month later I was in a VCS parking lot when I heard a HOOONK HOONK. Turns out some guy had sort of cut he same exactly same truck off, more like he made a left lane shift abruptly to make a left turn in time. Which isn't cool, but the guy turned left and parked in the lot I was in, and the truck guy stopped, totally obstructing traffic, got out of his car, and started screaming and flicking the guy off. He stood there and just keep screaming and flicking the guy off and kept doing it until the guy parked and looked and was like whoa, what the hell, he kept making sure to make eye contact. the victimized guy was looking at me like, what do I do? I wasn't sure. The same crazy guy, red in the red face, looked like he was about to have an aneurism, just stood there in the middle of s straight lane, screaming and double flicking the guy off, for like 10 minutes, which people were forced to go to one land and drive around him. It was so crazy. I thought about 50% he was gonna get a gun, I was looking for a place to hide. He just just kept screaming until the guy went inside and finally he just drove off. It was so wild. Various people were stopped and staring, it was a huge scene, I don't think I've ever seen anyone so enraged. It's like damn, I actually got rear ended around here and was 500% nicer to the guy. For watever reason that guy just wanted to rage at someone. It's bullshit, fuck people like that, That's the kind of guy that shoots up a 10 year old in traffic...
