All Audi's I've seen, except for e-Tron have physical controls and don't require the screen. And being able to hide it seems like a perfectly fine option for the times when you don't need it. When you actually can adjust AC, radio, etc. with real knobs, and aren't using the map, why do you need it? Might as well be abler to hide it.
Not only that, but when you also have the Audi virtual cockpit, you still have an always-on display, which covers many of the functions available from the center screen. I like being able to retract the screen on demand, particularly on longer trips.
Seriously? Giving user an option is a bad thing now?
Granted, on mine it is not motorized, but still, when I was driving at night on I-80 through Nevada, where as long as you do not manage to go off road navigation system just tells you "keep going straight for the next 600 miles" I liked turning the screen off altogether.
