While bicycles are popular, it is hard to imagine that human-pedaled versions will become a norm. It is impossible to imagine them used in a heat of Miami, or Atlanta (Georgia), or in Moscow. There well populated and mild-weathered megalopolis (London, most southern CA, north east China) -- but the speed, distance and volume of participants -- just do not make bicycles practical. I think the long solution is really de-urbanization of these megacities that act like a country-within-a-country. On a separate note, I find the use of word 'platform' (even in quotes) is unfortunate. Platforms, I though, mean something that provides composeable building blocks + principles for a variety of yet-to-be-anticipated needs.
