Teslas have a mere two buttons and are generally a joy to use. Why? Because the UI/UX was taken seriously, and the cpu hardware wasn't sourced from the dolllar store. This combination resulted in a screen-only experience that is responsive and easy to use (if you disagree with this, I will point you to Tesla's consumer satisfaction ratings, which say otherwise).

Every other car manufacturer followed suit, but made a critical mistake in that they only saw the cost savings in not needing to manufacture and build a bunch of switches. They forgot to do the necessary UI/UX work, and fitted their vehicles with a cpu out of a TI-83.

The reason why consumers are complaining about every other car manufacturer isn't because they have no buttons; it's because the screen-only experience isn't intuitive. Make it intuitive and the complaints go away.
