For me there's no set-and-forget-forever setting. Depending on the weather, how I'm dressed, how many other people in the car, whether there's a smelly diesel truck ahead, etc., that's a setting I need to change all the time.

I guess everyone is different, but what you described absolutely doesn't resonate with me. I never have adjusted my HVAC vents after their initial configuration. Winter, summer, whatever. I always want the air to flow the same way.

I practically never even adjust the AC. I set the thermostat and it handles itself regardless of if it's 110F or 10F outside.

Same. That's the beauty of automatic thermostats. They target the temperature you specify automatically. So you specify your favorite temperature once and never interact with them again.
