I do not mind having computer controlled running gear. But I want to own it. No live updates. No wireless network interface to the system software of any sort. GPL software only. I do not expect to get that soon.

No microcontroller there, just some vacuum linkages. Maybe a bit of electronics to turn things on and off, the switch certainly felt like an electric switch. None of these things require a microcontroller. Because it's cheaper, almost all of them use a microcontroller on modern cars; thermostats on lower models would probably be the most likely to be a simple system without a microcontroller.

    You can save a lot of cabling when you have central message bus shared by different components where a microcontroller decides whether a particular message is meant for this solenoid or that motor.

      you also have a single point of failure, which is a double-edged sword.

  Yes.. I had a 1986 BMW that had central locking, electric windows, radio, power steering, cruise control and a thermostat (which, as OP said, mechanical anyway). No microcontroller on that car[1]; it was a very reliable car too (bought it with 50000km, sold it with 270000km and only ever did services. Nothing broke in that time). Bosch k-jetronic fuel injection, no microcontroller needed.
