But you can do car sharing with any kind of car. In Germany there are cities that run a rent service for their citizens who only need a car occasionally.

Obviously this only works in the context of a robust public transport infrastructure and in cities built for humans rather than cars, so that the need for a car becomes a rare occurrence.

American cities don’t generally fit that description and until they do the type of car they use won’t change a thing, because it’s not addressing the core problem.
