Via: Copenhagen cycle chic
"A little urban detail that is oft overlooked or even unnoticed in Copenhagen is the metal on the poles at traffic lights. As the Copenhagener in the photo illustrates, it is often easier to just lean against the walk signal pole while waiting for the light. So many people do it that the metal on all the poles along bike lanes at intersections is worn and smooth from hundreds of thousands of hands.
A bike culture version of rubbing the Buddha's tummy."
