True today. But Uber's value is in the human component and the alternative's cost of ownership. Google and Elon Musk look well positioned crush Uber in the 5-yr timeframe.
What is Elon going to do? If you're talking about the Hyperloop, you're deluding yourself if you think that's going to be wide spread in 5 years. It'll take at least 10 for a functional scale prototype and then decades of NIMBY (Not In My BackYard) battles to get them built around the country. Even after that, it'll be like an airport. You can't have a hyperloop with 37 stops...it'll only be so fast and easy if it has a minimum amount of stops. At which point, Uber can help close the loop from hyperloop stop to your home or office.
Sure, but it's more like Tesla would buy Uber, not Uber would rocafella out and buy Tesla, along with the roads. Plus, outside of SF, Uber isn't really taking off.
