why aren’t elevators standard where you can deselect buttons?

Question

It seems to be so easy to implement and everybody knows the problem: you take an elevator, you click the wrong floor and now you have to wait awkwardly on the wrong floor for the doors to close again.

Answer 1

I haven seen elevators that do that, but they are quite new and most elevators at least were I live a often a few decades old and they arent going to replace them just for this new feature and adding it to old ones isnt a priorty. Not sure what the average life span of an elevator is but in 30 or so years I expect to see them much more.
