How does a shared car not need those items? It is just not under your management and is accounted somewhere else. But they are needed and you are paying for it. The only advantage could be that you're not paying with your own time and then it depends on what is cheaper, your work time or that maintenance time.

A shared car can see more usage, spreading the fixed costs (production, land use for parking etc) over more people.
