Over a century ago, street sweeping was only performed by municipalities that had an “above and beyond” drive to maintain aesthetic and safety goals as well as to remove large amounts of filth and garbage lining downtown city streets. Cities that relied on tourism didn’t want to be viewed as a dirty city that would turn people off from coming back. Also, any debris on the road surface from nails to rocks could potential cause a flat tire to an automobile or bicycle or get thrown up by a car’s tire and break a window, or worse hit a pedestrian.
