I don't think that's the whole truth. Berlin is still special in Germany and has a high cab density.

Actually you need a cab license to drive a cab in most german cities. And the number of these licenses is limited by the city. While the German taxi system is in dire need of a reform most people believe Uber is not the answer.

UberBlack is operating legally as "Mietwagen mit Fahrer" which is less regulated (doesn't need the taxi license), but UberPop doesn't even fulfill those lower requirements.
