Travelers hail a disproportionate amount of taxis. Living in a walkable European city with good public transport, approximately the only times I use taxis or Uber are when I'm going to/from the airport/train station and have luggage, or when it's a business trip and I can expense it (and even then I opt for trains when I can).
And the parent commenter mentioned that they usually get a taxi from the airport at least (because it's right there I guess, there are strict special regulations about how german taxis wait at the airport to make things go smoothly), so... Another other reason to take one is when you're so far outside and at a time of day that public transport is spotty.
In markets like Frankfurt and London, Uber has a tougher time competing. Totally agreed. It still has niches. And most taxi markets aren’t filled with lovely, knowledgeable, ambitious drivers.
