The argument is that self-driving cars would reuse existing roads, fuel, service, and manufacturing infrastructures that have been developed for existing cars. And, adoption can be incremental. Start with cars which drive themselves highway only, and require a capable driver to be at the wheel at all times. That may be soon. Gradually add more use cases at the speed of engineering, regulation, and social acceptance.
Some of the hard things to change in the world are hard because they require many people to change their behavior in coordination. Cars to self-driving cars doesn't. Email to Email with innovative clients doesn't. Introducing a new communication protocol does (though of course it's not impossible). Of course, this is only one aspect of a complex world.
