He's a prick OP.
His sad little ego. So have you tried to address this via that? When we are in the car and a knob like your H tries to "assert his authority" whole car comments now how big his willy must be or, more accurately, how little you must have in your life to be such a road knob.
But it's not just his driving, it's his "right of way" and being a stubborn prick with his kids with cyclists, pedestrian crossings, prams, it's part of some immature god complex, it must be, amongst other things, so tedious.
Decent men try to help situations so we can all share this planet equally.
We live next to a "I know my rights" knob. Everyone has deserted him so he gets to play with his little motorbikes alone now.
Your H belittles his dad.
He puts his kids in harm's way
As you don't sound like you want to leave him you can only hope dashcams and cameras stop him before he hurts someone.
Then all his rage will be in the house only.
Why his parents don't tell him to fuck off us beyond me.
Do you find this attractive OP?
I would be telling him that he was far from attractive every time he was an aggressive car knob. I would be ever so sarcastic "does your willy feel bigger now dear". "Oh they must be thinking what a prince amongst car drivers"
We see some amazing drivers, calm, considered, see a hazard on the motorway and put hazards on help make others around, behind them fully aware and slow in time. They are the princes on the road. We always say "oh well done blue car beautiful driving" the aggressive, selfish knobs we just think god your life must be so small and who the fuck has sex with you.
Perhaps comment on others amazing driving, others kindness and actions that contribute to public spaces not make them worse. I mean that is if you prefer those type of drivers.
