We'd also avoid a lot of accidents if we stopped the people that are doing lane changes for position-jockeying and no other purpose.

So it's bad to be mad while driving, but there's a lot of lane changes that deserve the ire. (It's a tiny fraction of drivers that get really bad, but a less tiny fraction of lane changes.)

Being angry at them won't change their behaviour, but will make you more stressed. Remember: driving like that is its own punishment, because they'll be extremely angry and frustrated at everything. Between that and the realisation that driving 2% slower adds about 1 minute more per hour of driving you have to do, I find I can avoid stressing at people lane weaving and have a nicer journey myself.

> Being angry at them won't change their behaviour

Yes, but the comment above was about society collectively making a decision, so that's the context I responded in.

And while it's relaxing to not worry about your own exact speed, I don't see how that lets you avoid stressing about the people that are lane-weaving. They're acting dangerously and I need to be ready to react to them.

Unless they careened into your vehicle while making the lane change, just calmly allow your vehicle to drift away from theirs until you have a safe buffer again, and take joy in the fact that it didn’t meaningfully impact your arrival time, but you’ve meaningfully impacted the safety of your immediate surroundings.

How about you let the police do the enforcement, and focus on your own driving?
