[image: an old UK traffic light button that says “pedestrians, push button and wait for signal opposite”, with the word “wait” illuminated by a bulb and an explanation of pedestrian traffic signals].
Reblogging that post about traffic light buttons made me realise a perseveration really suddenly. This is how traffic lights were when I was a kid, and that wasn’t very long ago. Many are probably still like this, but new ones aren’t. The text explains to the pedestrians how traffic lights work!
People I went to school with used to speed up (or slow down?) the little spinning part underneath, as apparently (erroneously) that made them stop the traffic faster. The new ones don’t have that spinning part.
And the signs didn’t have “walk” or “don’t walk” on them Americans!
(I bet that’s just a stereotype)
