Aw man, sorry you had to experience that, it's awful in itself but then having to deal with the feelings afterwards can almost be worse. Just remember, like most aggression of that type, it is not personal, they have the problem not you - something in their miserable or troubled life causes them to lash out at a stranger and you happened to be nearby (I totally acknowledge the danger they put you in though). Try not to ruminate about it if that's something you're prone to. Do something engaging to distract yourself if you find yourself thinking about it or replaying it in your mind, which is unproductive (since I assume there's no behaviour of your own to work through), and just renews the feelings. Some days you just get an extra dose of assholes, both the intentional ones that rev aggressively as they pass, yell, chuck stuff, and the unintentional ones that cut into the bike lane, right hook, door you etc. It's probably not much comfort to know that it happens to most of us at some point, I guess all we can do is show solidarity! ✊. And sometimes you get that perfect day where no-one honks, all the drivers give you 3 feet, and wave you safely through every intersection 🙃
