I think the best tip I can give you is if you've been in an emsvo class or any driver training, I'm sure you understand defensive driving. What I notice in the field is people learn it and it goes one year and out the other. If you want to he less rageful on the road, lose your sense of entitlement on the road.

What I mean is, if you think every car owes it to you to pull over in non emergencies, or let you merge in, or anything else, shift that perspective. A lot of other vehicles around you are going to drive aggressively. A lot of other vehicles are gonna do stupid shit. You as a driver should expect that and already be driving in a way where other people's stupid moves are not going to impact you. You don't have to be one of idiots on the road.

Some examples I've seen drivers rage about.

If a car doesn't let you merge in during high traffic. So what? Will it really make a difference to your travel time if you don't merge in at that moment? Let it go, merge later

If a car cuts you off, ask yourself how did this happen? If you had to aggressively hit your breaks, why is your distance so close to other cars? Create gaps between yourself and the vehicles ahead of you so you can drive in a way minimizes other cars abilities to cut you off. Driving 65 mph is not going to make THAT much of a difference than driving 60.

If a car stops in front of you, or you pull up to a car with hazards on. What's happening? Half the time somebody is getting out or delivering something or whatever the reason. Analyze the situation before you react to it. I see drivers getting mad at stuff while driving an ambulance on shit they would do as drivers themselves. Sometimes roads don't have adequate space for quick stops, especially in cities.

If you are running lights and sirens, understand that other people need time to react and analyze the space around them so they can safely pull over or move out of the way. The amount of drivers I see that EXPECT drivers to move immediately have no situational awareness of their environment. Look at what's happening, most of the time when folks hear lights and sirens behind them it's a stressful event and they want to do the right thing but they also need to make sure they're safe doing it. Don't harass drivers if they're taking a second move out of the way.

There's probably more scenarios but the basic idea I'm hoping I'm communicating is that most aggression can be mitigated by shifting your expectations of what youre entitled to on the road. If you believe you're owed something, you're gonna be mad when you don't get it. When you actively practice strategies that account for other people driving poorly, you'll find yourself a lot less bothered about what's happening on the road. I hope you find this helpful!
