Ride-hailing, also called ridesourcing, and codified in California law as Transportation Network Companies, are taxi-like commercial transportation services based on the use of an online platform that connects riders with drivers and automates reservations and payment. Ride-hailing services may offer a variety of service classes and vehicle sizes, generally using passenger vehicles or Sports Utility Vehicles (SUVs). In larger markets, a shared service class may be offered, in which unrelated passengers travel together for some part of their trip. Though the terms are often used interchangeably, ride-hailing is distinct from ridesharing, which refers to non-commercial sharing of journeys by drivers and passengers traveling to the same destination, as in carpooling, slugging, or vanpooling [1].
