The biggest problem I always have with elevators is not the algorithm, it's the people seemingly being unable to grasp the concept of pressing either the up or the down request button, depending on where they want to go. Almost always I find someone will press both, because "then the elevator comes faster". Completely ignoring the fact that they end up going the wrong way first half the time, and adding an unnecessary halt for everyone already in there. How hard can it be to understand?..
And then when the elevator door opens, they ask the people inside: "Are you going up or down?" There's an arrow showing that, for Christ's sake.
Yeah and you can flail your head around looking for the arrow or you can just ask. Especially on a busy elevator lobby there might be multiple cars opening at the same time so you cant even tell from the ding/ding-ding
or just point your eyes a few degrees away to look at the dedicated arrows next to each elevator, built for this exact use case, which indicate whether that specific elevator is going up or down?
I have to assume this is a cultural difference and you just don't have those indicators where you live, rather than "slightly moving my eyes is too hard, better make my problem into somebody else's problem"
