My suggestion is this... Convert elevators to banks in major large buildings that warrant it, These should be obvious. Into banks. With multiple elevators handwaved as being there.
Meaning if someone gets in on a floor, they press the call button, a door opens and they get in. That door remains open... But keyly, when the elevator moves, the next person who comes along, can then immediately call and open the door again and get into their own dynamic elevator room. And head down or up of their own volition.
You could also have a max number of elevators that can be moving, per building. And so on, but that's not the core of this idea.
It doesn't make sense that everybody uses the EXACT same elevator in a building that is supposed to house 10,000+ workers is servicing all of them.
