Situation: You have 5 minutes to make your train. You are about to enter Penn Station and you are presented with the stairs on one side and 2 escalators going down on the other. Which is faster?
Optimal solution: The left hand side of the escalator , when sane people are riding it, is reserved for those who choose to maximize the escalator by walking down it. You fly down that sucker , lickity split, no shit.
