For the way I use the screens, to all intents and purposes they are passive while I'm driving. I don't have a need (or want) to touch them at all while the car is moving. I set up my map route before I pull off, often on the phone before I get in the car, then that's it for the rest of the trip.

Controls for everything else like AC, volume, switching radio station/track is not needing to be done with the screen, it's all through classic buttons/knobs or steering wheel controls. I would not buy a car which required the screen to be touched for these things.

I don't see anything objectively more or less dangerous about operating a radio in this way, the only real difference is that instead of your radio frequency being visible through 7 segment displays, it's now on a high resolution display.
