Comment on Undo codes for Japanese elevator floor buttonsparent

Comments

In the USA 99% of people press the "close door" button immediately upon entering, without looking whether someone else is currently headed to the same elevator. It makes sense to disable a button that people can't use politely.

How do you know they don't just do it because they're used to the door not closing immediately?

Does it matter in a situation, where you don't want to close the door immediately?

They are, and it doesn't. I don't understand your point.

They press the close door button because they know they have the time to turn around, notice someone else entering and press the open door button.
