Small-Scale Question Sunday for May 21, 2023

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

Culture war topics are accepted, and proposals for a better intro post are appreciated.

Elevator buttons do nothing. The door doesn't close any faster if you press the button but it gives you something to do.

This one is definitely not true. I've timed how long doors take to close normally, and then validated that pushing the button will immediately close (ahead of the normal time). It could be true for some elevators, but it's not true for all (and the theory doesn't qualify its claim as being only about a subset of elevators).

This is correct. Even on older models the control panel is highly configurable by the owner/operator. The primary purpose of the firefighter key/code is to unlock full control of the panel for emergency services or a technician. In the US most of them will be in a rather restricted configuration considering our special mix of idiocy and litigiousness.

Which continent do you live on? I've convinced myself that elevator door close buttons only work about 10% of the time in North America and the rest of the world but about 90% of the time in East Asia. Maybe I'm just more inclined to follow rules and expect things to work in East Asia though.

I live in Northern Europe and if there is a button to close the doors in the first place (there isn”& always), it works much more often than not.

I live in the US.

They work almost all of the time in South Asia. I was aware of the 'myth' in question, but unquestionably validated that they did do what they advertised pretty much everytime I checked.
