I am all for improved govt services based on smart data and IOT. But you did not address the elephant in the room, which is privacy. Many users would be displeased if the government knows the kind of data uber collects — their travel patterns. Granted, Uber could provide low resolution, anonymous data. Nonetheless, I don’t think it is the technology or will, so much as policy or legal discussions, that is the largest challenge between here and smart cities.
