As someone of a similar age, I can definitely say this is not true for everybody.
Raging at the idiot who pulled in front of you solves nothing.
It’s not like we don’t know that. Otherwise OP wouldn’t have the self awareness to ask the question. It’s just an emotional reaction to people, situations, and actions that defy logic. I get angry at drivers when they do things that are not only blatantly selfish and inconsiderate, but dangerous and usually illegal (in SoCal that’s every few minutes). I don’t know about OP, but I’m not doing any “raging.” No one looking over at me would know I’m angry af, but I’m sitting there wondering how the US is filled with so many sociopathic freaks and why we’re all ok with the way we treat each other. And picturing what would happen had I done the same thing in traffic. A cop would materialize out of nowhere, or the other person would jump out of their car with a bat. But the people who cut me off? They never see any consequences, and if any one of them learns their lesson, there’s ten more willfully ignorant, dangerously stupid people to put everyone else at risk. I’m not attributing anything to malice. Cluelessness is so much worse, and people should be held accountable for not learning from their mistakes. Besides, being considerate, responsible, generally respectful, and empathetic does not require any extra education or intelligence (though it would certainly help). Somehow, the universe is totally fine with all of this, and so is everyone else. I was in a bad accident years ago because someone pulled right out in front of me, so I’ve lived through the consequences of some selfish prick valuing their two seconds of time over other people’s actual lives. If a teenager acted the way we act collectively, as a population, their parents would be told they have behavioral problems. You can not react all you want, but that doesn’t help anything going on under the surface. Mindfulness and stoicism is just living with the anger and stress instead of solving it. That’s why cognitive behavioral therapy is the only thing that will actually help it.
