do condo elevators have to move to the bottom floor, empty, when current riders are thru?

Question

We were told that they must go to the bottom floor, empty every time they are empty a few seconds after being vacated. Why can't they stay where vacated until a new rider asks for it to come to his floor?

Answer 1

I think this just has to do with a decsion made by the people who installed the elevator. The question is where does it make the most sense for an elevator to wait for the next passenger. This is a common problem for people who must make these decisions.
