Much of anarchist praxis relies on direct action, so mostly it only functions well in systems where there is a possibility. In the case of the carpool system, I suppose that folks could start more conversations (to use an example), and the way that gets introduced is that individual folks start trying it and seeing if it works. Or folks could make other changes and see how they are received. However, the lack of changes means that folks who use the system every day can be thought of as making a choice to reify the "rules" of the system- they just keep doing that which is working for them and other people. Hence, "anyone" could introduce improvements and it really is the case that "everyone" is running the system.
