Yeah I agree it's like the subway in that sense. I just have trouble wrapping my mind around how a shared driver-less car economy would work, especially when it comes to the role of government vs. companies. For example, who would maintain and repair all the cars? Who makes sure that the interior of cars are kept clean and in working order? Would car design become totally commoditized? Cars are a form of self-expression for many, what will people do if all cars are shared and driver-less? I'm not saying this to be cynical, I'm just genuinely curious how all this might play out. When you think about how much time people would save and how many industries would be changed or created, I think it's possible that shared/public driver-less cars might be just as revolutionary as mobile devices and the internet, or at least in the same ballpark.
