I remember seeing something similar to this not so long ago here on HN - especially regarding the crosswalk buttons.

>More than 2,500 of the 3,250 walk buttons that still exist function essentially as mechanical placebos, city figures show. Any benefit from them is only imagined.

This is justification that you should keep pressing the button. Even if only 750~ of them actually function, that's more than 0 from not pressing the button.
