I'm not sure how exactly it's done in Germany, but in Lithuania "black cars" main difference from "taxi" is "black car" have to agree on price before the ride while "taxi" works out the price after the ride.

Uber is currently enjoying third way there thanks to political support (which may or may not be related to Uber IT operations located in town). But overall it (and it's local competitors) are gravitating towards taxi side of things. Taxi license is dirt cheap though. The only issue is yearly (vs bi-yearly) car inspection and more expensive insurance.
