I guess I wasn't clear enough. Let me try again. Google has been in the self driving car business since 2009. Uber was FOUNDED in 2009. Google has a history of starting cool projects, which never make it to market (Wave, Video, Glass, etc.)... That alone, doesn't inspire much confidence that their self driving car project will reach production. Uber has the incentive, far more than Google, to actually see this through. If they can cut out drivers, their overhead shrinks significantly and their core business grows.
