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.
