It’s not wise to get into aggression with other drivers, too, even if they messed up. If you want to be aggressive with strangers, you are risking a fight. That is a fact of life. I don’t feel sorry for you if you get the fight you are looking for.
On and off the road, I have on many occasions come to a rapid boil, said or done things I normally wouldn't do, and deeply regretted it.
I have had my own share of road rage incidents, tailgating, playing chicken, etc.
When I was a young man, a guy pulled out in front of me unexpectedly causing me to spin out and end up in a snow bank. In astonishment, I turned to see him flip the bird at me! I ended up getting out of that snow bank, running him down to where he was stopped at a busy intersection, and jumped out of my car while it was still moving and it ran into the back of his car.
When the guy got out, I grabbed him by the lapel with one hand, and reared my fist back with the other hand to slug him as he babbled incoherently.
He was pointing at something with his eyes bugging out, and I realized I had gone down a one way street by accident and he thought I was turning into his street as people who deliberately went down that street occasionally did. We ended up being able to talk and shook hands, but all these years (35) later, I still think of that. Who knows what would have happened. I could have injured or killed him with a punch and gone to jail. My life would have turned out so differently.
I have made a concerted effort with some success to master my temper. I have managed to be able to drive without getting overly angry at some transgression by another driver. Tailgating used to drive me mad, but now, I can, with good nature, just pull over.
I am only a few years behind that poor vet who was beaten up, but I have been better at this for some years now, and I am constantly on guard against backsliding. It is ongoing, as my experience yesterday shows. I should have governed my tongue and walked away.
But I try.
