Imagine if they achieve economies of scale and started introducing buses instead of cars. Imagine they improve efficiency by driving routes as requested by customers in realtime. Imagine if they were to charge customers based on how much it actually costs them to drive in real time so each customer can decide if its worth it based on their own needs. I can definitely see that such a world will be a lot more efficient in terms of transportation costs and time. If it requires subsidies so that they can achieve that economies of scale, so be it.
