Traffic lights
Quicky: to continue my observations regarding traffic lights, over here they are almost strictly on a timer creating “waves” of traffic, you could say.
This is unusual to me because in the Netherlands there are detectors in the road, which sense if there’s traffic waiting. Only then will that particular lane get a green light shortly thereafter.
Similarly for pedestrians, in the Netherlands they press buttons to indicate they want to cross the street.
Only once or twice have I been at an intersection of crossing here, where I had to push a button to wait for a green light.
