Apple Map&#x2F;Siri and Google map eventually will become the interface to ordering car sharing. Especially once there is autonomous cars and Uber or Lyft do not own the driver-side of the equation, ride sharing will become a bit like ordering rental cars from Kayak.<p>The same way Facebook is becoming the interface to content, both google and apple will own the consumer side of the cars and help you pick the best deal or cheapest option. It could be from Uber, a guy who owns a fleet of 20 autonomous cars or Hertz, etc.<p>This moves totally makes sense for Apple as they will move to own the consumer side of this market.
