Funny, as much as I like (and use) GM’s auto headlights, I still use the switch all the time.
Two reasons: I back into our driveway and as soon as I’m parked I like to kill the lights so they’re not shining excessively into the house across the street. Second, I like to use the parking lights when appropriate.
They’re both just a courtesy thing, but the switch is right there, so why not? But I’m sure I wouldn’t bother it would be a huge PITA if it meant tapping through a bunch of menus on the screen.
