At least not without drastic downsides. What are you basing this on, and why would you say it as if it is obvious? This is exactly the sort of weird fatalism the GP is talking about. There are already a billion cars on the planet, which is enough for 7 billion people with autonomous self-driving. 90% of US households own a car and the rest of the world will catch up with US wealth within a century. Even current-day-tech electric cars and nuclear power could be used to power them without carbon (at large expense but one that could be afforded after a century of economic growth).
