> no more pranking anyone by pushing all the buttons (because you can only do that while waiting for one and the system will dispatch the demanded floors to the pool) While it would stop pranking it opens it up to denial of service. Most new elevators don't let you select more floors than the persoson capacity of the cab. With the external keypad system someone could hide on a floor with nobody around and keep entering floor numbers. Incidentslly, I was on a full elevator when a kid pressed all the buttons and ran out (this was before the protection I mentioned became popular). I could hear the groans of my fellow passengers. Fortunately I was shown a trick by an elevator tech for that brand a few weeks ago. I held the door open and reached up and tripped the door switch. All the lit buttons went out and I just aelected my floor again. Got a round of thank yous as everyone else selected their floor again. > you can't change your mind once you're in. Best case is you can stop at an intermediate floor if someone is going there or called the elevator. That could be rage inducing. Imagine forgetting something in your car and being stuck going up to the top of a very tall building. And then going all the way back down. There really should be a button for "let me off at the next valid floor". I'd hate to be stuck in an elevator when someone gets sick and has to hurl or worse shit their pants.
