BMWs actually use a dial that you can rotate in the centre console of the vehicle. It's actually very intuitive and easy to use, and a _lot_ less distracting than a touchscreen is.
You know that this dial has a touch screen on top and you can draw with it? For example, it supposed to ocr letters for nav location. No idea who uses that...
When do you need to use that dial while driving? It's exclusively useful for things that you should only do while stationary.
