I was confused by this "LOOK" algo... I'm American and I've lived all over the place, and I'm not familiar with elevators that pick you up on the way up if you pushed the down button. As far as my experience, they only pick you up on the way back down. To the extent that if I did hit the down button and got in and it went up, I'd think I'd gotten in the wrong elevator or there had been a mistake.
