This is the problem - if the system goes beyond “what floor should I idle at” and “do I idle door open” people get mad at it because of apparent unfairness and inefficiency even if it is actually more efficient overall.

Same thing happens with traffic lights.

This got downvoted, but I’m pretty sure it is objectively correct. I feel like the same sentiment occurs with one queue vs multiple queues.

Continued small motion in a long single queue feels “fairer” than multiple queues - and may actually be.

But I also know most people prefer a driving trip where they’re continually moving rather than one where they’re basically stopped - even if the second is shorter in time.

“Apparent fairness” is an important design criteria for dealing with the public. Even if the system is actually incredibly unfair.
