MY IDEA IS "ELEVATOR TOILETS" TO STOP PEOPLE FROM PISSING ON THE FLOOR, SO CRAZY IT JUST MIGHT WORK

Boston will be trying out sensors in elevators to detect urine because they seem to have a problem with people pissing in them which is gross and unhealthy so a cleaning crew has to be used every time it's done and these sensors will do just that, contact the cleaning crew, not stop people from pissing on the floor

It might be cheaper and healthier to either put a port a potty outside elevators or a built in toilet on the inside for those that just can't hold it and left their towel at home ;-)
