It may be the case in NYC that they are not wired. I travel a fair bit, and am not willing to say, categorically, that none of them work.
So I have a choice. I can press the button and have it do nothing. The light will change of its own accord and I have given up … I’m not sure what? If the button is wired, then odds are good that I have just saved myself a lot of time, standing at an intersection, cussing the %$#@ light for not changing.
Seems to me I win either way, since the effort invested in pushing the button is fairly minimal and I am assured that the light will change in all possible instances.
