That is a really good way to draw some crushing fines and law-enforcement attention; the FAA is not a local taxi committee, and they do take seriously the safety of bystanders. That said, if you want to take that route, build out ops in less-regulated countries. Iirc, that's part of the reason Zipline started scaling in Africa (along with greater need).
Sorry, did Uber actually deliver any value other than crashing wages, bargaining power, and working conditions for taxi drivers?
Unbelievable value to its customers, yeah. That's often the point of a business.
A slight price decrease versus other taxi services is "unbelievable value"?
What an odd dismissal. I don't know where you're based, but in most of the US the experience of hailing a cab vs getting an Uber is night and day. The ease of use, the ratings, the price transparency, the availability - are all way superior, price doesn't even come into this. I grabbed a taxi recently and got quickly reminded of what it was like with "sorry, the credit card machine is broken" BS. No thank you.
Getting a taxi was a pretty unpleasant experience before Uber. Are they still evil, sure. But taxis were worse.
