Oh I have a 10 years old VW with both buttons and touchscreen. I tell you, the buttons you can learn and they're the same across similar VW models, but as soon as you have to do anything with the displays (the big one in the cockpit and the small one on the board) things go downhill immediately. I don't know who designed such UX, but I wonder, do they have the nerve to put it in their CVs?
