I don't understand why my temperament while driving becomes incredibly aggressive when I'm driving manual instead of an automatic. It's like all of a sudden everybody is too slow and in my way

I want to say maybe it's because I get annoyed when I can't upshift/forced to downshift because of the car in front of me. I have to say it's taking a hit on my mileage everytime I rev to show a car I'm pissed off 😭 I'm trying to be nicer for the sake of Mt car, but does anybody else experience this?

Edit: Thanks for sobering me up guys. I realize I'm being too self-centered and not considering other drivers. Like, I know I hate when others ride my ass, so I probably look like an idiot doing that myself. I'll save the revving for the empty streets
