In the spirit of genuine curiosity, who is making you feel like less of a person wrt the choice of main/master, and how are they doing that?

It sounds like you're saying that git maintainers are intending for you to feel like less of a person because you don't agree with their choice, but I don't understand how you arrived at that conclusion.

A train can go from "cruising speed" to letting passengers off to escape a fire in about a minute.

A plane might take anywhere from five minutes to several hours to be able to safely let passengers out.

Personally I feel that's a good enough reason to impose more robust restrictions on Things Which May Cause Fire on planes compared to trains. Especially in the case of lithium batteries where they're more or less impossible to extinguish one they're going.

> most people in my life react negatively if I express emotion that what they are doing is upsetting

Right. I guess they feel accused, as though you're attacking their behaviour rather than sharing how it makes you feel, and instinctively become defensive in response?

It's wonderful to meet people who don't think this way. My partner is incredible at this, I can tell her "when you X I feel Y" and know without a doubt her reaction will come from a place of trying to work together to understand whether the problem and solution exist in X, Y or both.

The recommended 3 second gap is a much bigger distance than most people recognise, especially at high speed.

On another note- I feel sad that you could tell your mate "the way you're driving is making me uncomfortable" and be met with basically "your discomfort isn't valid because [technology] so I won't change my behaviour".
