General Motors' Cruise autonomous vehicle unit said it will remove human backup drivers from the driverless vehicles it is testing on San Francisco streets by year's end, as California's Department of Motor Vehicles has granted the company a permit to do so. This follows Google subsidiary Waymo's announcement last week that it would open its autonomous ride-hailing service in Phoenix, AZ, without human drivers. Said the University of California, Berkeley's Steven Shladover, "I don't see them as revolutionary steps, but they're part of this step-by-step progress toward getting the technology to be able to work under a wider range of conditions."
