Elevator as a detour? Yes, you might need to wait for it. But you might need to wait for a traffic light, too. And in many cities (able-bodied) pedestrians don't have any issues with using stairs.
Four, try eight, at a standard four arm intersection.
Although many places where overpasses are used, not all legs have ramps, which is something which makes overpasses more feasible, so two or four may be more common.
Elevators are extremely expensive to operate and maintain.
