It's a huge difference when travelling. I really learned to appreciate Uber when I was in a foreign country, and could, _without local knowledge_, summon a car for a reasonable price and high confidence that I wouldn't get scammed. Interestingly, the Uber was also consistently way cheaper (think "half or less") than unlicensed local bike taxis, so I suspect that it does provide a value to the drivers too (maybe not having to stand around on a corner hoping for a customer for hours). Meanwhile, in Germany alone, you'd need to have multiple apps depending on which city you're in with little consistency between them.
