This is the Airbus v Boeing problem. There are two schools of thought, one being that you the operator can control all the settings including the ones necessary to avoid the fogging. There are others that do so automatically. So many times people would be aggravated that my a/c would turn on with the heat in my Audi. What they didn’t realize was how that prevented fogging of the windows which inevitably would happen a few min later. I noticed my current car also does this but it turns itself on after the heat has kicked in.

Automatic things are annoying IF the user isn't sure what is happening or why.

Heat randomly turns on -> human is confused, maybe uncomfortable, and might think the car is broken/haunted.

Heat randomly turns on, car displays "Preventing windshield fogging" -> human is thankful car is thinking ahead.

Except that displaying unexpected content interrupts the driver’s attention and takes it way from where it needs to be.

It’s certainly not important enough to distract someone performing any delicate maneuver.

Thats why a good notification system comes in different levels. Like red and big for important messages, blue and small for information like "heating windshield".

This is a false dichotomy.
