It's similar to when everyone claimed that touchscreens on phones wouldn't work. They were right until they weren't. Touchscreens on phones didn't work until Apple fixed that. Tesla has done a proper job on car touchscreen UX, but everyone else is putting out garbage.
Sure, phones are a marvel ans show what you can do with touchscreen apps but that is nothing like driving. I also can't play games on a phone well without a controller (or keyboard and mouse for FPS) for the same reason (computer aim/walking assistance is cheating, why bother?!). I use an external mechanical keyboard even when on the road (Keychron K7) because I don't find even the M1 Macbook Pro's keyboard good enough for real work.
So yeah, the touchscreen puts me off getting a Tesla (alongside a bunch of other cars) almost as much as the amount of remote control they have over their cars. No thanks, as much as I love the idea of owning a Tesla.
I’m not fanatical about this, I would use it if I would be forced by circumstances. But I would not be happy about it. And I still would try to educate/convince older colleagues that hotkeys make things quicker/easier/“reliabler”.
From your speculation of source of touchscreen hate, I see that you feel that tesla has superior car touchscreen experience. And I don't doubt that. But however good you can be with touchscreen, you can do even better if you also have bunch of physical buttons (in addition to touchscreen/must look then point device).
That's not a good analogy. The main interface to the car is not the controls/screen, it's the steering wheel and pedals. The controls and screen are interacted with only intermittently. There is more information available allowing for automating most of the controls, and voice control for the rest, meaning the screen is mostly just used for visualization and the occasional action.
