On the other hand, we will see a sharp decline in human-driven cars on the streets. Who would do it themself anyway? At every moment we will have on the streets exactly the number of cars to serve current demand. They will not clog curb parking places - there's no point for driverless car just to stay there for nothing. They will not roam free - there's no point for that too. They will stay in the cheapest, ergo most inaccessible for humans places waiting for orders.
