Here's an interesting rumor. It seems that if you simultaneously press the 'door close' button and a floor button in an elevator, the elevator will go into 'express mode' and proceed directly to the selected floor without stopping at any other floors. Could be a useful trick if true, but I can't imagine that it actually works. I don't even think repeatedly hitting 'door close' would prevent an elevator from initially opening at a floor. I've written to the Otis elevator company to see what they have to say about this rumor. I'll report back if I get a response from them.
