I'm with you on this one. I think perhaps my favorite car interface to date is my '01 Camry. Let's look at the HVAC system: Three knobs: temperature, speed, vent selection. Three buttons: a/c, recirc, rear defroster. That's it. The entire system. It's a 20 year old design at this point. I have never once thought that I, a mere mortal, could improve on the design in any meaningful way. The buttons and knobs are big enough that I can work them w/ my huge gloves on, I do not need special gloves that work w/ a touchscreen, the buttons are not context sensitive, and I can hit all the controls in the dark without even looking. Another point, which I've now learned I had taken for granted, is that no software update will ever mess w/ my muscle memory. Those switches cannot be programmed to do anything else in software, as they're physically wired to the functions they control. The beauty of the system above is that the physical controls are the state machine. I can literally feel the state the HVAC system is in. Nowadays that state machine is all in software, and I have to hunt through menus, look at a display, sometimes multiple displays, just to figure out what state I left the system in. That's just unacceptable.
