My bf’s anger seems very unhealthy

My (25f) boyfriend (28m) and I have been together for a few years and live together and I’m really starting to think he has a serious anger problem. He has way more than just a short fuse as he often goes from 0 to 100 over what I believe are really small (but valid) sources of frustration. I’ll share some examples. We live in a city and drivers are genuinely rude sometimes but he’ll also get set off my a slow driver or full Trader Joe’s parking lot or other people being kinda dumb on the roads and absolutely blow up. Cursing, hitting the steering wheel, honking, the whole nine yards. And what makes me really uncomfortable is (before I said this really bothered me and firmly told him to stop) he would see that it was a female driver and call her a c*nt for whatever merely annoying thing she was doing. He also gets frustrated by coworkers “spamming” him with multiple requests in separate, consecutive emails in a short period of time. Or he’s having a bad day and his AirPods disconnecting is the last effing straw and there goes the cursing again. I try to get him to breathe, step away, realize the moment is fleeting, etc and he never wants to hear it. The other day he slammed his hand down on the table at a bar because the guy running trivia started reading questions before we could get into the google form. It was so embarrassing. Me saying anything or expressing my own disappointment in this behavior just riles him up more. Idk what to do.

EDIT: I want to be clear that he doesn’t verbally or emotionally abuse me and I’m not worried about this escalating to violence or anything. He seriously doesn’t have it in him to hurt another person.
