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.
