> But I also noticed that some new cars ship with infotainment systems that consist solely of a (bad) touchscreen; as new cars slowly replace old ones, the number of cars with actual physical buttons for the music player or radio is dwindling. This is awful because the lack of physical buttons prevents the tactile feedback needed to operate the device without having to look at it.

This is a huge issue. I'm fortunate that my car's infotainment system is controlled by buttons & knobs; I worry about folks in e.g. Teslas who are forced to take their eyes off the road.
