I've seen them work ok in an office building with ~15 floors and 6 elevators until lunch time, when the extra traffic made them take far longer than it seemed t

  I'm sure it's more than that: The express lifts remain for too long at the "key" floors to pick up more people. This is probably some energy vs practicality balance that can be adjusted, and that we're very likely guilty of. The normal lifts will happily depart with nobody inside if you don't sprint to them because the consoles are 25ft away. You book 2 adjacent floors, you get 2 lifts scheduled for only those floors. So much for saving energy, and also, now 2 lifts are busy instead of 1. The fancy giant touchscreens are a nightmare: small touch targets, 80% of the screen devoted to static diagrams, the resistive touch film already failed in the hot spots, esp. because you are forced to touch some areas even though you have no choice!! (Choose north or south tower. Oh you chose the south tower but you're in the north one. Sorry you can't do that). I could go on... but, in a nutshell: these people can do hardware. They fail big time at software, both the scheduling engine and the UI.
