I really disagree here. I think the biggest strength of Uber's business model is that they offload all of the maintenance, fuel, liability, registration, etc. costs (as well as the cost of managing all of that) to the drivers. In addition, local regulators have been treating Uber with kid gloves in a lot of markets because Uber "creates jobs"; when Uber starts getting in the business of putting drivers, both their own and drivers for other companies, out of work, I wouldn't be surprised if a lot of markets start making it even harder for them to operate. Don't get me wrong, I'm very excited for autonomous cars, and absolutely think they will be omnipresent in the long-term future, but I don't think Uber will be the company that dominates that market, at least not in the short-to-medium term, and trying to do so will be their Waterloo.
