Waymo said Wednesday it has applied for a permit to test its autonomous vehicles in New York City, the Alphabet company’s first step in a sticky regulatory process to bring its robotaxis to U.S.’s largest city.

Waymo is currently operating a robotaxi fleet of 1,500 vehicles in four markets: San Francisco and the Bay Area, Los Angeles, Phoenix, and Austin. It plans on launching a commercial service in Atlanta later this year, as well as Miami and Washington, DC. The company has said it will add an additional 2,000 vehicles to its fleet through 2026.

Waymo is bringing autonomous cars back to New York City for tests, with the hopes of eventually offering a paid ride-hailing service.
