Elon Musk's Robotaxi Vision: Why Private Car Sharing Will Not Work

In fact, robotaxis are already being used in initial cities. Companies like Waymo demonstrate that autonomous mobility is technically feasible. However, Musk goes a step further with his vision of decentralized, private car sharing. According to this idea, individual Tesla owners should be able to profitably operate their vehicles in a kind of personal rental model. The realization of this idea, however, is associated with significant challenges.

High Risk, Low Utilization

A central factor for the profitability of car-sharing services is the vehicle utilization. Studies show that a vehicle is only profitable if it is constantly in operation. But this is precisely where a private robotaxi model could reach its limits: Consistently high demand is not guaranteed.

In addition, the issue of vehicle maintenance must be considered. Vandalism, pollution, or minor damages already pose a challenge for professional car-sharing companies. For private operators without a central maintenance structure, it is likely to be difficult to keep their vehicles in an economically viable condition. The hypothesis that private individuals could carry out the autonomous maintenance and repair of multiple vehicles independently proves to be unrealistic. While professional providers can rely on their own service teams or external service providers, private operators would have to perform cleaning, maintenance, and repairs themselves, which would involve a considerable amount of effort.

Legal Uncertainties

In addition to the economic hurdles, the legal framework is also unclear. In particular, the question of liability remains unresolved. Who bears the responsibility if an autonomously driving vehicle causes an accident? Is the fault with the owner, the manufacturer, or the software developer? This is still a topic of intensive discussion, especially in Europe.

The car-sharing market is characterized by high competitive pressure. According to a study by the management consultancy Berylls Strategy Advisors, about 70 percent of providers are not profitable. Smaller, local initiatives, in particular, face low margins or deficits. Therefore, the profitability of the business model greatly depends on a professional infrastructure and a large fleet.
