I recently drove a friend's Mercedes and the hard part wasn't the touchscreen but rather the input device. On the center console there were some physical buttons and levers, and on the steering wheel column there were multiple dials. The problem was that what I thought should have been the gear shifter was instead conceptually a "mouse" for navigating the on screen menu options. Thankfully I only needed to drive the car a few miles, as one friend had already given up on driving the car and asked me to take the wheel instead - she was that frustrated by the controls! Could be that I'd get used to it, but it wasn't a good first experience.
