Continuing along the transportation theme, let us talk about the moped. A friend of mine had noted how unusual it was to see people riding mopeds in DC. Yet in the rest of the world in metropolitan areas mopeds are quite a common form of transport. So why don't we see more mopeds on the streets of DC? Is it just not socially acceptable or "cool"? Is DC not congested enough to warrant the use of mopeds? Is gasoline to cheap?
