Well, they obviously need someplace to park the cars, and the cars obviously need to get charged periodically (which is likely to require human intervention), and it may be useful to have in-house service capacity. But a combination of internal monitoring systems to detect cabin issues that require a stop for cleaning, and stops for charging and service (that can also be leveraged for in-person cabin and exterior cosmetic inspections) seems to address this, and may require less cost and less risk of forces outside the company's control than relying on individual owners.
