I had to make a throwaway as well just because I couldn't believe this comment. This is so utterly false. You're essentially claiming that the value of these services is all based on the innovation of the _hailing_ functionality, but there are countless apps that recreate this functionality _exactly_ whether for 'regular' taxis or separately licensed cars. If what you want is for a driver to come to your exact location very quickly, you can get that _anywhere_. This, as a business model alone, is like Dennis on 30 Rock with his basement coffee business. It's so easy an ubiquitious that it's not worth mentioning as a differentiator _at all_.
Separately from this, it ignores the fact that there are cost-based reasons for these kinds of behaviors. Drivers, for example, have to think about round-trip cost. If you ask me to drive you from Washington Sq. Park to Astoria, I have to think about what fare to charge you such that it covers my expenses on the longer trip _as well as_ the likely problem of not picking up a return fare that takes me back to a high-traffic area.
This is all discussed with much greater statistical depth in the Naked Capitalism articles on Uber, but the basic problem is that none of the ride hailing services have found a way to make this any cheaper, except through massive subsidy (to pay drivers to be the ride stock in low-profitability zones they others wouldn't be in). And even with an innovation like self-driving cars, it would only make a difference if it is not a commodity. If it is a commodity (which, IMO, is the overwhelmingly most likely outcome for self-driving cars), then either Ubers completely captures all relevant IP for end-to-end commercial solutions ahead of any competitiors, or else Uber is licensing out the cars just like everyone else, and for whatever cost reduction it buys them for getting rid of drivers, it just creates a new price war race to the bottom on who can charge the least for the self-driving based rides.
I'm just so tired of all the mental gymnastics defending them. It really is total ownership of all IP for commercial self-driving cars or bust for this business model.
And if it busts, you'll see that all the niceties you describe in this comment are mostly the product of either (a) massive investor subsidy, or (b) easy and cheap-to-copy innovations like a map and location-enabled hailing app.
