Re: OMG .... It's ridesharing?
No, that app allows Uber to run an unsantioned commercial taxi service. It might be contrued as "ride-sharing" if it were used by people to find others who happened to be going the same way so they could share the costs of the trip.
Much as the current licensing regimes for most industries being invaded by the "sharing economy" need to be reformed, they exist (or, at least, existed at one time) for good reasons, in many cases related to health and safety. It should not be up to the likes of Uber and Airbnb to just rip up the rulebooks because they're not convenient to the "sharing" business model.
