Oh yes I was not commenting on any of that. Data privacy and the reliability of computer hardware and software over time are separate issues.
I was just speaking from the basic-level user experience of operating a vehicle- touch screens are terrible. Pretty much everything you want to do in a car should have 3 requirements:
Keep your eyes on the road. Controls need to be in consistent locations and have some other way of communicating what they are and what their status is non-visually. Dials, knobs, buttons that lock in-or-out, switches, levers, sliders. Anything close together needs to be differentiated- buttons with different textures, shapes, or resistance for example. This is very difficult and almost antithetical to touchscreens. The strength of the touchscreens is their flexibility- they can have deep menus that re-use a small amount of space efficiently, but the trade-off is that they need the user’s vision to work.
Non-visual feedback to the user for their activation. Touch screens CAN do this with haptics and sounds. And there are physical inputs where this can be a problem, like regular buttons or knobs with uniform shapes. Levers, sliders, switches, and dials have this as inherent properties
Response time. Touch screens on vehicles are usually underpowered and seem to take seconds to register an input, then apply it. If the music changes and is suddenly way too loud, it’s annoying to be subjected to that for 5 seconds while navigating the touch screen and waiting for it to work, in contrast to a regular old volume potentiometer that operates basically instantly. Really any music or audio controls can get really annoying with delay, though I’ll admit those are a luxury. Things like the lights are not.
Not a requirement, but cars should be judged on whether these things FEEL good. Touch screens have improved slightly over time with better materials and haptics, but that only applies to higher-end ones and still isn’t great. Cheap physical inputs can suck too, though they are usually still better than touch screens.
