My experience with "sharing economy" taxi companies is that they really, truly, do not care about their drivers or their customers. It's a free for all where customers and drivers are basically left to sort things out themselves. IMO, this is where regulation comes in. In a city like New York, taxis are a part of our public infrastructure -- like buses, subways, etc. There should be baseline service guarantees set by transit regulators and adequate funding set aside for enforcement.
