You don't have to stick with the same person. Ask for a consult and if you aren't vibing with them just move on.
Social workers, counsellors, therapists are trained to talk through these things and understand your thought process. There are basic needs every human has, and you'd be surprised how they can help you with your own introspection.
It can be mock conversations or real ones, you can talk about how you would typically act or respond to people, and they will help you understand others possible perspectives.
No, it's being an asshole and thinking your shit matters more. I'm not sure what you're even arguing at this point. We're clearly agreeing that zipper merging is most effective, but if you leave a lane to cut back in 1 or 2 cars ahead, you're an asshole.
I don't care about people merging who have been in the closing lane for some time, I was pretty sure the original reply was talking about the people who leave the flow of traffic to speed ahead when they know the lane will close. If you're already in flowing traffic is there a benefit to zooming ahead and cutting someone off?
If lane 2 is closed ahead, and you're in lane 1, I think it's a jerk move to leave lane 1 to try to rush ahead a few cars and cut someone off when you need back into lane 1
