I don't like how uber flaunts the law in so many places, but their competitive advantage doesn't come from non-compliance.
The service is plainly better. The cars are better, the drivers are rated, payment is easier, hailing is easier, knowing where your cab is and how long it will be and how much is will cost before you start your ride ... is better.
I live in the Twin Cities ... not a place where cabs are dense enough to just hail one walking down the street (unless it's in a prime drinking/sporting hour & location).
Uber, Lyft, and the city of Minneapolis worked together to make uber-like services legal while giving concessions to the local traditional taxi drivers without compromising appropriate regulations. Everyone behaved reasonably which is sadly extremely rare everywhere else.
The running theory is that unreasonable people either leave Minnesota or are found only after the snow thaws (please don't take this too seriously :) )
