Not so sure about the elevator part. Depends on the elevator. The elevator in my building in NY has functional open and close buttons. http://www.pbs.org/wgbh/

  Um there are working buttons in the elevators I describe, just on a timer. Most of the time its on a timer if active even.

  For the most part, the open and close door buttons are there for use by firefighters. If you're a fire fighter using an elevator you don't want the doors to automatically open or close when you get to a questionable floor. When the fire key is turned the doors are manually controlled and only respond to those buttons. Otherwise, the Open door button is for people wanting to feel good and the Close door button might as well be controlled by Schrodinger cat.

    Not sure why you were downvoted, but this is false as others have pointed out here. Adding another data point: The close button on the elevator in this building here works as expected. Press it, door closes _right away_. Don't press it, wait for the doors to close in a couple of seconds.
