Watch Waymo remove safety drivers from autonomous taxis for the first time

Phoenix, Arizona is home to the world's first fully driverless robot taxi service.

Google sibling Waymo now has driverless cars on public roads, with no one behind the wheel.

The autonomous Chrysler Pacifica minivans had kept safety drivers onboard, ready to take over in emergencies or when the vehicle fails to navigate on its own.

But Waymo has let its cars off the leash in Phoenix, AZ, giving them permission to drive entirely on their own. A demonstration video published on November 7 shows the cars providing lifts to passengers in the back seats. No one sits in the front seat.

Waymo, which is owned by Google parent Alphabet, says it will soon be using the vehicles as part of a ride-hailing service. Starting in a small metro area of Phoenix for now, Waymo says it will operate its fully driverless cars in an area the size of Greater London, spanning approximately 600 square miles.
