> The future for self driving cars are closed roads where only driverless cars are allowed.
This is the present in Honolulu, as of last year: a fleet of self driving cars, operating on a closed road where only driverless cars are allowed, transports over 3000 people per day. The service is called "Skyline".
I looked it up and it seems to just be a typical driverless train, more or less the same as is found in airports for changing terminals, except that this is longer than those. It might be a good service, but not quite as exciting as your description.
Well, yes: it was a tongue-in-cheek way to observe that requiring closed roads for self-driving vehicles would render the whole exercise pointless. We already have a more efficient solution for that problem, with no need for any exciting new technology!
On a larger scale: Copenhagen and Vancouver both have fully-automated metro systems (i.e. driverless systems). Presumably there are many other cities with such systems around the world, and they probably all work nicely.
Fine for getting around different areas of the cities, but it's not going to drive you wherever you want to go though.
