I wonder why mopeds have never taken off in the US. Seems more practical than a scooter for medium to long distances within a city. I have relatives in Taiwan and mopeds are everywhere there (and other parts of Asia).
I think cars a cheaper relatively in the USA also a lot of places I believe you need to pass the test for a full bike licence. That is a 900 -1200cc super bike that can do a very good time round the TT course or the ring.
