> Personally, I really enjoy that with our new van I can listen to a podcast/music through Bluetooth and pause/resume playback through a simple touchscreen without having to fiddle with my phone directly.

I'm not sure what your point is. I never said that no one wants these features. Obviously there are many that do.

Attach your phone to a holder. Buy a Bluetooth adapter from AliExpress and your good to go with any car

Exactly. I don't see why a screen attached to the car is somehow superior to the native screen I've been using for years; just put it somewhere accessible. I've found that the CD player mounted phone holders are insanely convenient in almost every car.
