A taxi service that is hired like Uber and Lyft but has no driver. Although some self-driving cabs use existing self-driving vehicles that have steering wheels while the service is in test mode, future self-driving cabs have no steering wheel and no human driver. For example, new Waymo vehicles have no steering wheel, brakes or gas pedals. See
Cybercab,
Waymo and
Zoox. See also
