Well, that's an interesting problem to solve.

In the situation you propose, you have would-be car owners who now share a car. That eliminates the pollution involved in the manufacturing of one car from the story. And yes, if the car had to make back and forth trips from a central location, that would be inefficient. But I think the idea is to have a network of shared infrastructure (similar to uber), so that if someone needs a car, they can have access to the closest available one.

Even for uber-like car sharing/pooling, each car will have to travel more, and occasionally will be driving empty (when autonomous).
