The Paris street scene video above makes me think of my observation and experience in the orient.
Consider the word, "LANE," in the phrases, lane-splitting and lane-filtering (as well as, lane-sharing).
Roads and streets in Seoul, South Korea, have LANES, evidenced by white paint on the pavement signifying their presence. However, the only result I observed from this lane marking was, a COLOSSAL WASTE OF WHITE PAINT! (Comment not exclusive to motorcycles; rather, universal to ALL vehicles.)
