Obvious in hindsight. This sort of thing is inevitable any time you have dumb software on one side and humans on the other side. I'm mostly a fan of these non-taxi "taxi" services, but it seems like they are slowly and painfully rediscovering why taxis ended up so regulated in the first place.
There's a lot I don't understand about Uber. What's the Uber business case? Is there enough profit in taxi services around the world to justify their valuation and financial losses? Do they hope to recoup through a future monopoly? Tracking Data? Self-driving vehicle fleets?
Now it seems to be, avoiding regulation for fun & profit.
