clearly they aren't using "destination dispatch" where the elevator tells you where to wait after you tell it where you want to go. https://en.wikipedia.org/wiki/Destination_dispatch I've only seen this in one building. It was a little weird, but it supposedly is coming soon to more and more elevators.

I stayed at a hotel that used this. It's a very nice, efficient system. Much better than everybody cramming into the next elevator that arrives and selecting a bunch of floors.

Yes of course it’s by design. I just wonder why.

Because you could deselect other peoples choices.

How do I go about deselecting other people's choices, if that's my specific goal? I can get whatever I want in Jira, but nothing in elevators. It's fucked.

Might be a bit off-topic… But: The one big question I have with elevator UX is this: why isn’t it possible to deselect a choice? So pressed 10th floor but wanted 11th. There is no way to press button 10 and then button 11 to correct that mistake. Will I ever solve this mystery?

Because in a busy environment (where consistently more than one person uses the elevator) the scenario of making a wrong decision and having the wish to correct it occurs far less than the scenario where someone does not pay attention to which floors have been selected already and deselects your destination. At the worst case this means that you both miss your stop because you both did not notice.

Not worth complicating the UX to address such a minor issue.

This is it exactly. It opens up the door to even more complexity in the design...

Now that you can unselect floors, if the elevator is on its way to the 5th floor and you unselect it, should it skip that floor mid-movement?

If there's only one floor selected, we'll probably want to disallow unselecting it while the elevator is moving, but what if you just hopped on and it hasn't moved yet?

This would probably make for an interesting interview question.
