I love StreetFilms! There is nothing like the visual to cause one to reconsider what one thinks one knows. And here is a film short on 20 mph speeds on residential streets in England, the 20 is Plenty, For Us campaign. Most of the streets shown either were narrow to begin with, or have traffic calming measures installed, so our widest streets in Carson City would need something done to them to make this practical. Just imagine, though, drivers and bicyclists and pedestrians sharing streets as common space rather than funnels for impatience and pollution.
