Waymo has gotten the green light from New York City to start testing autonomous vehicles on its streets.

Waymo secured a permit from New York City on Friday to test its autonomous vehicles on the city’s streets, days after New Yorkers reported spotting some of Waymo’s distinctive cars driving around Manhattan, though the vehicles had human drivers.

NYC has granted Waymo permission to test a limited number of autonomous vehicles, as long as there's a driver behind the wheel.
