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.

Because other people will unselect the button you just pushed so they can get to their floor faster, and fights will break out.

We have such elevators here, and I never saw such fights.
However, I think the real reason is that they are harder to program (and obviously require more modern hardware, e.g. not just an ordinary set of mechanical buttons) so unless it’s time to renovate the apartment block elevator no one cares enough to replace them.

It *is* standard, and has been for 20 years, in South Korea and Japan.
Anyone saying it would be expensive or technically difficult is talking nonsense.
Elevators with “elevator car cancellation” are no more expensive or difficult to implement since elevators switched over to computer control about 20-ish years ago.
Why isn’t it standard all over the world?
I can only guess the answer is apathy or cultural differences, but I don’t know the details.

Used to have one of these in our local shopping centre, people would often get in, unpress every floor other than the one they wanted to get off at and then people would start yelling as soon as it skipped their floor. The place is shut down now but I don’t miss those lifts one bit.

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.
