Efficient mobility services constitute essential prerequisites for making cities sustainable, both economically and ecologically. Widespread accessibility to mobile communication has given rise to a number of new ride-hailing services. Yet, many services, in particular classic taxis, still operate based on first-come-first-served basis. Combining a statistical physics analysis with data-driven modeling, we demonstrate the intrinsic inefficiency of such a service. Given a fixed number of taxis, the system can handle only a limited number of requests. Once this capacity is reached, the system not only overloads, it also stays overloaded until the request rate decreases substantially below the onset rate of overload. This hysteresis effectively reduces the capacity of the service by up to 50% compared to ideal operation. We illustrate how both, clever route pre-planning and including ride-sharing, remove this inefficiency and may contribute to fair and efficient mobility in the future.
