    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?..

      I don't think I've ever seen someone do that

        Because most buildings now they just put one button so people stop clicking both

          What? I’ve never seen that. The elevator needs to know which way you want to go.

            On the ground/lowest floor, there's only one button as there's only one way to go.

              And the top floor too

              That’s not what they meant…
