my car key does something similar, it unfolds the side mirror then opens the puddle lamp so you could see near the door area.
but it does not open the door automatically, which i think is not safe.
and i do not know about high end cars, but what i know is that the hood is more mechanical so if you pop it open you have to push down to close it (not like the trunk where some can close it automatically). imagine if you go in front and the hood opens
of course, they could have though of all these and makes thinks easier , as much as i don't like apple, they do have a knack for improving things
