Maps? Android Auto / CarPlay? Gotta have the screen anyway for the mandatory backup camera.
We can have both! Physical buttons for everything that doesn't actually benefit from having a display, (like music or heat/ac), touch screen for the rest.
Just like my 2019 Hyundai Ioniq. Buttons for the car stuff and a touchscreen for media, calls, navigation, backup camera, etc.
If the touchscreen were to shit the bed I'd still have a fully functional car minus the backup camera.
