Rex might have been a bit blunt here. But he's right. If you want to stop raging, then you -and only you- have to do the stopping. I'm afraid it could take years. But it's worthwhile and you'll enjoy the small victories along the way.

I was suspicious, too, of your original post. To me it didn't seem like bragging. But I wondered if you weren't just writing something outrageous just to watch the spit hit the fan. But it seems that your post was sincere and that you do want to stop. In that case I say 'cool'. It's a good idea. Raging is not only unhelpful, it's actually wasteful. We really do have better things to do when we're out there on the roads.

I can remember, say, thirty years ago when I'd yell and shake my fist and stuff like that. But I (slowly) realized that I was better off paying attention to the others who were entering our mutual-sphere-of-influence. (As opposed to the idiot who did something stupid, but is now taking off like a bat out of hell.) Most of them aren't going to do anything rotten. But every single one of them needs to be watched. It's one of the reasons that driving is no longer any fun for me. Probably the biggest reason.

Of course, when you're on a bicycle you have a similar issue; you really, really need to watch them all very, very closely. But for some reason, it's less aggravating on a bike. I don't really have an explanation for that. But I'm glad for it.

Now on a scooter you are in a worst-of-both-worlds situation. You can not exit traffic and follow alternate routes like a bicycle can. You're stuck in traffic and you're a tempting target for bullies and for those jerks who don't pay enough attention. In this case you might actually have to be sort of raging. But you need to make it more of an act and try to repress it as a feeling. Try to have 'command presence', as they call it. When someone acts like they're going to try to take your place from you, then scowl and look 'em right in the eye. Maybe even point at them and say (or mouth) 'Don't do it!' This won't cover all situations you'll face, of course. But you'll figure out how to handle more and more situations and you'll feel good when you make these small victories.

Good luck out there.
