My 2019 Tesla has all of those except the power off button, and windshield defroster. It doesnt have a emergency system anywhere so not relevant.
Do any EVs have a power off button that actually powers it down? There is an option in the menus on the Tesla but thats still not a full true power off.
My BYD Atto 2 only has a physical power button, no touchscreen power off. (and an app, but that's another matter)
What happens if you power it down, do you need to press the button to get the car to activate beyond opening doors / 12v stuff?
Yes. A few automatic things like lights staying on until you've locked the car, windows auto closing, but otherwise pretty much what you'd expect from turning a key. Doors are manual, so that's not affected.
