Suddenly, we can have real-time knowledge of the whereabouts of all modes of transportation. We can plan, quickly pay for and seamlessly connect any combination (well, not perfectly yet, but you can see that coming). And the range of these transportation possibilities is multiplying fast: train, bus, car, scooter, bike; owned by the city, companies or individuals; available by the minute, hour or day; driven by you or driven by others; parked by you or parked by others.
