Motor or vacuum driven ventilation controls. That don't work. Just give me cable controls, want defrost? Slide the defrost control. Floor vent or dash vent? Slide their knobs. Want some of each? Slide the appropriate one. They last forever and give the ultimate control.
I'll agree that vacuum driven climate controls are stupid. But if the system is designed well, motor driven controls are just fine. If they're built decently, they last a long time. And I'll take a well configured auto climate control system over constantly needing to fuss with the HVAC controls to keep the car comfortable.
I've got a pair of 20+ year old auto climate systems parked in the garage, both of which still work perfectly fine. The Jeep one is a decent implementation, certainly good enough to be better than manual controls (and more reliable than the vacuum controls they used on manual HVAC versions of that Jeep).
The BMW auto climate is almost as good as a house thermostat. Pretty much set the temperature and other than telling it if I need window defrosting, I often go months without touching the HVAC panel because it knows its job well enough. And that system has also been reliable.
Those systems are more complex than the cables, but a well engineered system will have diagnostic ability if a problem comes up and should last a long time. Like anything else, it needs to have enough functional advantage to justify the complexity, but I'd say that at least the good implementations do. And in 13 years of owning the Jeep, I've never had to touch the auto climate system. Only things I've done were a blower motor resistor, heater core, and A/C evap. In other words, parts that are present and still fail on the simplest of climate control setups.

I am not sure I understand what you are getting at. To me it is simple. It is not ok to use a touch screen on your phone that many people have fixed to their dash but at the same time, it is perfectly ok to use the touch screen that the car manufacturer affixed to the dash. Both play music, do GPS stuff and make phone calls. Hell, I can look at all kinds of engine and systems-related info on my phone in real time. The same info you can pull up on a touch screen in most cars. Why is it ok to use touch screens that are part of the car but using the touch screen on a phone gets you a nice ticket and points on your license?
Use of the built-in touchscreen may not be enforced, but it absolutely fits into many distracted driving laws. And a cop could ticket you for it if they felt like it.
