Not any cars in any cities anywhere near me.  I don't think most people
around hre, for example, would use an open 12MPH scooter for a year-round,
10+ mile commute -- and that's in a medium-small city.  We have snow,
rain, winds, traffic, and I haven't noticed my house moving any closer to
my office (or anywhere near my office suddenly becoming a viable pace to
live).

Maybe food delivery in LA or someting, but...  well, those people already
use mopeds and such that cost one heckuva lot less to own and operate.
What do you think those fancy flat NiMH or NiCd batteries are going to
cost to replace every year or two?
