automatic mirror

I just saw somebody get out of their car and the car automatically pushed the mirror in closer to the body of the car, so that anybody parking wouldn't accidentally hit the mirror. I never noticed that before. I'm used to cars beeping when you push the lock button and I remember I had a car that locked automatically when she close the door and of course some cars turn the lights off after a couple seconds, and some cars turn the radio off and I think all cars turn the air conditioning off when you shut off the motor. What else can they do for us?
