It's ridiculous that any of these things need microcontrollers. My first car's door had a little joystick that physically moved the mirror around, presumably using pushrods or something. The door lock was a physical device you moved up and down, and had a motor connected (power door locks were fancy). It also had cranked window controls, not so nice. But power windows didn't need a computer either.

We keep taking things that worked fine without a computer, adding a computer, and ending up with all the problems of a computer but with little extra benefit to the user.
