Touch screens are terrible to use while driving, especially for frequent operations (volume, change stations, climate control, hazard lights, wipers, etc). The current trend is to push more into these touch interfaces, but most car manufactures have still left some of the more important ones as physical buttons.

For tesla the matter is not ergonomics, but simply cost.

Wipers are automatic, volume, stations and fan speed are on the steering wheel (aling with voice control at other setting. at least on my Model S)

I love automatic wipers. They turn on in the wierdest situations. Particularly when you've been on a road trip and your windshield is covered with a nice smattering of bug guts.

They are pretty good on the Tesla, and i believe have even gotten better, with over the air software updates :).

Thats why you have the two scroll-wheel knobs on the steering wheel. You select a function and then you can adjust them with a physical control while driving.

"terrible" seems overdramatizing. "Slightly inconvenient at first, but fairly convenient a few weeks down the road after the muscle memory develops" is a more apt description. Volume and wipers have been duplicated to steering wheel knobs and levers, hazard lights do have a physical button (as electrical system failure and touch screen outage are a possibility), and climate control defaults to the last desired temperature (and that's if you chose to go off auto).
