Manufacturers definitely went wrong putting important controls in the touch screen. That’s a usability nightmare. I’d consider the rest to be personal preference.
As far as the "questionable utility goes", I frankly love it. I love just walking up to my car and having it unlock for me. Sure, it's not much, but it's kind of the equivalent of Touch ID or Face ID on a phone these days. Sure, entering a PIN code isn't the hardest thing in the world, but it's the little things that make life just a smidge less annoying, right?
You didn't address my point regarding their ubiquity now, so I feel like you kinda decided to only address half my point...
I'm not sure I'd consider permanent connectivity and the related telemetry and OTA updates to be personal preference. These are often being used in ways contrary to the owner's or driver's interests, from invading privacy to "licensing" vehicle features that can be disabled later, and they come with significant security and safety risks.
- No bluetooth.
- No touchscreens.
- Really, no screens at all.
- Cabled audio input.
A rearview camera is a good thing, except it still manages to make the car worse overall because the manufacturers somehow can't stop themselves from using the screen to display other things that should have been displayed in another way.
