  Placebo buttons in pedestrian crossing street lights are plain evil. Also, https://xkcd.com/277/ https://xkcd.com/277/

    But also not 100% the case. Where I live (Calgary, AB) most cross walk signals are only activated by pressing the button. If you don't press the button, you just get the orange hand the whole time.

      True, and same with the button to keep the door open in elevators. Both where huge surprises to me when I moved here.

  After discovering this it has become a habit to check elevator buttons to see if they are real or placebo.
