I could not imagine having to go back to buttons for anything I actually want to control. Once you get used to a well-designed touchscreen, buttons are just so clunky and unintuitive for most functions. Dials are probably my most favorite physical control, but other than volume there's not much it's useful for in a well-designed, modern car anymore. It was great for radio stations, but is terrible for Spotify.

Setting temperature manually by dial doesn't make sense anymore either- most cars have too many things to change and an expanding menu is great. There's hot cold, faster fan lower fan, feet vs head-height (we're already looking at more than three separate controls). Now there's seat heating and cooling (with varying power), steering wheel, defrost, controls of vent direction, etc.

I'll admit the touchscreen might be daunting if it's a rental but it takes like one week to get everything mapped out mentally (and going back to physical controls on rentals sucks).
