A total swap out to driverless cars would mean social change in ways not being discussed. Driver's licenses will not be needed. Highway Patrol will not be needed, or at least, not so many. That means traffic court will be a historical vestige. And "licensing fees" (a favorite of Silicon Valley software developers) will be required rather than ownership. The cars will record illegal use and sale of drugs, discharge of firearms (drive by), and many other illegal things traditionally done inside cars. Parental controls could be applied.
That's not so bad. It's no different than expectations for workplace behavior.
For those who postulate we are running out of resources to lubricate and fuel our vehicles, take a brighter approach. All renewable energy can be used. Synthetic plastics? New Zealand has been using 10% sheep fat as crude oil for a long time - hurray for carnivorous activity! We will finally get lean cuts of meat because all the fat will be directed to synthetic lubricants and plastics. Wood, shell and rock will still be around to make whatever. And best of all in this hypothetical future, luthiers can give up their power tools!
All due to driverless cars :: the panacea and savior of the warming world!
