Radio has different UIs for setting up (finding) stations, making lists of favorites etc. Great on a touchscreen. Just cycling presets doesn’t need a touchscreen and I’d assume almost all modern cars even do that on the steering wheel (volume up down and track/channel step).
Right but I thought you were arguing "Just don’t use ”infotainment” when driving" and these are still part of the infotainment systems. No need to throw out everything just because of touchscreens.
