I found a "mode" in an elevator in India that I have not seen anywhere else: if a destination floor number is highlighted, and you press it twice, it gets cancelled. I have used this magic power just once, when an obnoxious man got on and insisted on having a loud conversation on his phone. Since he wasn't paying attention, I double-tapped his floor number and made him skip. I happened to get off at the floor before his, so the elevator went down to the first floor after dropping me off. Small pleasures....

I believe your story highlights precisely why more elevators don't include that functionality.

No it doesn't. You can't prevent people from being a-holes and stealthily pressing 10 buttons before leaving the elevator. The feature as described is as useful as pressing a floor to stop on. Perhaps it makes more sense on smaller elevators than it does in large ones. Or perhaps it would make more sense to allow undoing a press only within the first few seconds.

In at least one elevator I rode in as a kid, pressing every button resulted in everything being de-selected.

In South Korea, pretty much all elevators have this enabled. Pressing a floor button a second time cancels the request. It's pretty useful (if not abused).

This could be a nice "learning" trick too: sometimes, you see people pressing angrily on buttons many times when they are in a hurry, this teaches them to cool down, don't press the button many times, it won't help.

I literally used that feature earlier today in an elevator in Thailand. The exact method of operation seems to vary among elevators, some require you to hold it, others require more than 2 presses. It's great when you change your mind.

This has made my day. I have spent much of the last decade campaigning to anyone who would listen for the existence of a feature such of this to nullify accidental button presses in an elevator.

In my experience in Asia it's about 50-50 chance that it's either double-press, long press or second press that cancels it or that it's not enabled.

you can have phone conversations in a lift cabin? don't they act like faraday cages? I always lose connection in mine.
