In Germany: while taxis are required to have licenses, we don't have such things as taxi drivers renting their medallions for a day.
> and abide by other silly regulations
Regulations usually exist for good reasons. Let's just take the common complaints about the German ones:
- cab drivers have rigorous tests on their knowledge of the city's streets: you don't want to have drivers which are stuck on the side of the road if their GPS fails and also you don't want them spend a minute idling and typing the destination in the GPS. Furthermore, it makes for a more professional experience.
- cab drivers have to know lots of tourist info (this applies at least for Munich, Berlin and Hamburg): you don't want to have cab drivers unable to at least explain a bit about the city. Cab drivers are, airport staff aside, the first point of contact for tourists.
- cab drivers have to keep their car clean and maintained: once again: Cab drivers are, airport staff aside, the first point of contact for tourists. Which means that an unclean, falling-to-pieces cab will leave a negative impression on the city as a whole. Also, not properly maintained cabs are a safety risk.
- cab drivers from city A may drive passengers to city B, but not pick up passengers in city B. Once again, this is not just to protect taxi drivers in city B (because the meter in taxi A may have lower tariffs), but also to ensure a competent driver for passengers in city B.
Uber didn't grab much of a hold in Germany because the cabs here are not the total desaster that is found in other countries. Especially, we have the Beförderungspflicht, which means that a cab driver must transport you inside the licensed area, no matter how short or long the route, and especially discrimination on race or the 'hood where the passenger is hailing the cab is forbidden. The only reason for a cab driver to deny you transportation is if you're too drunk/drugged or armed/aggressive (both of which are a danger to the cab driver) or the destination is outside the licensed area (the cab driver still may set his/her own price for such routes, but very well deny you transportation if it's too far away).
