Computers and timers now control the lights at many intersections, but at one time little buttons at crosswalks allowed people to trigger the signal change. Those buttons are mostly all disabled now, but the task of replacing or removing all of them was so great most cities just left them up. You still press them though, because the light eventually changes. Någon som vet hur det är i Sverige? Fungerar rödljusknapparna?
