Setting aside the specifics of the case, I do think that from a UI standpoint, cars either need to support being left in park without the climate control eventually cutting off or be so extremely clear that this will happen that it would be extremely difficult for a user to miss, as this is a legitimate example of a “fail-deadly” feature.
IIRC from reading comments from people who have slept in their car and very much want the ability to leave the climate control system active, at least some Toyota models do support leaving the climate control active for extended periods of time, but the car needs to be in “Ready” mode. It was not immediately obvious to users that this was the case.
I don’t know if I’d call it a favorite, but Time Cube is pretty iconic of Internet zaniness for a certain period. It went down in 2015, a decade ago now.
