Stop and Go, Rome
The streets of Rome during rush hour are awash with local pedestrians, curious tourists, uncountable numbers of scooters, and the occasional car driving at breakneck speeds. Surprisingly, nobody seems to get run over.
The shot of this traffic signal is somewhat contradictory. The light in the foreground indicates Stop, whereas the light across the road facing the same direction indicates Go. The net result (I presume) is that they cancel and everything just moves along at its own natural pace.
