Comment on Undo codes for Japanese elevator floor buttons

Comments

And on the opposite-of-polite side, supposedly there's cheat codes for bypassing floors where someone is waiting for the elevator.

This could actually be useful and "polite" when you are in a full elevator. Often times there will be a packed elevator going to ground but it needs to stop+open+wait+close on every floor even though nobody can fit in. This just reduces throughput and can make rush periods stretch on for a long time.

I've always wondered if elevators code detect when they were full and avoid stopping for outside requests. Some combination of total weight + weight change could likely be a heuristic that improves performance overall.

Does the elevator speaker play “GOD MODE” when you do that?

On some elevators you can hold the door shut button when the elevator stops at a floor to let someone on.
