>There is room in such a big market for many players. Big and small.
there is no real room for big players which is why Uber's business model is burning investment money and dodging regulations.
Have you ever seen a taxi monopoly? There is no scale effect to this business because adding more drivers and more taxis just drives your costs up linearly, and given the diseases big business suffers from and all the tech overhead of Uber it's probably worse than that.
That's why transportation like trucking or the cab industry is dominated by small business.
