Interesting idea but comically unsafe.
Lots of things from chain saws to hover mowers, or cars for that matter, are unsafe if not used with due regard for safety.
In Australia (and I would imagine elsewhere) Apartment complexes have a body corporate which all owners are voting members of, and they have to vote two annual costs: the operating fund, and the sinking fund. the latter has to pay for building maintenance such as painting, and lifts. These are the two notoriously most expensive repairs in the life of a modern building: a complete re-cabling of a set of lifts for even…
Interesting video. I've often wondered what the most optimal elevator algorithm is. Imagine a scenario where a single person calls an elevator to go down, and just as they get in, a group of five people on the floor above also call the elevator to go down. We all know that the elevator would go straight down and then come back up for the people who called the elevator too late. The elevator could actually save time b…
Concentrated harm and distributed benefit is a recipe to have a few vociferous complainers and many silent beneficiaries. People who believe they've suffered a grave injustice will be much louder. The best algorithm and least complaint-inducing algorithm are distinct.

A fascinating example of this with queuing humans is the Disney Fastpass system (1). I think the real design goal to avoid "complainers" is to try and optimize the wait time for your resource to avoid a bimodal distribution and try and spread it out for the average rider, rather than make wait times worse for the majority of people but better for the people who game the system.
(1) https://www.youtube.com/watch?v=9yjZpBq1XBE, yes this is an 1:45 long video on the history and a simulation of Disney parks, but its worth the payoff.

Why so much? They're important cables, but surely not made of unobtainium and not that rare of a product with the amount of elevators in existence.

Nobody likes being stopped at a red traffic light but we all understand they're a necessary evil so we don't crash and kill ourselves.

The trouble is that the call button doesn't indicate how many people want to go in a given direction, just that there's more than zero with such a desire. If you could get people to input perfect information about where they wanted to go (ideally on the way to the elevator lobby, before having arrived there), much greater optimization would be possible.

The "harm" in this case is potentially a few seconds added to an elevator ride. I think there is another psychological effect to consider. Once you've boarded an elevator, you're no longer really 'waiting'. Even if an elevator takes you on a longer trip than necessary it might not be as annoying as a longer elevator wait. And ultimately, elevators are not ran by democracy. If the algorithm benefits thousands of emplo…
