I definitely don't want my car controls tied to a phone app. No matter what I should be able to configure my car's functions long after the company stops distributing their app. But there's no reason why we can't have a "best of both worlds" sort of deal. I have a modern Mazda with a touch screen that comes with a center control knob and has physical controls for a good chunk of the settings you'd ever want to change while driving. So I don't have to go through menus to change my air conditioning from low to high, but I also don't have to use a tiny character led display and a "push 3 times, then hold for 5 seconds then pull twice and rotate 37.8 degrees" multi function button to find and access settings outside of those physical controls. In fact, the touch screen disables touch input at speed, so the control cluster MUST be able to access any functionality without relying on the touch display. It works pretty darn well. In fact the only thing I'd argue it could do better is be more responsive and have a decent set of distinct tones for navigating the screens without sight. It's not often I want a setting in the menus while driving, but it would be a lot nicer if each menu screen had a distinct set of sounds so that by ear I could know where I am and memorize those controls if I needed to.
