Hyundai is slowly backing away from the all-screen approach to interior design.
Hyundai Design North America Vice President Ha Hak-soo said that people "get stressed, annoyed and steamed when they want to control something in a pinch but are unable to do so."
Personally I prefer a mixture of both. Touch screen for anything you don't need to operate while driving and physical for everything else.
Android Auto navigation, car system/audio settings, clock and system management, etc should all be a touch screen so you aren't navigating through turning knobs and pressing up and down buttons to go through various menus like your programming a microwave.
Knobs and dials and buttons for anything to do with audio volume, skip/reverse tracks, etc. and air conditioning.
My Prius has a voice control option built in already. The only time I've ever activated it is by accident because it's a steering wheel button. It's a 2016 Prius so I doubt it's able to do a whole lot anyway. Thankfully, most of the controls do not require the touch screen or voice control. None of the essential ones do.
