Alphabet Inc.’s self-driving car firm, Waymo, said it will begin transporting passengers in a handful of cities near its Mountain View, California, headquarters.

Waymo has begun offering their self-driving ride services to select customers in Mountain View, Los Altos, Palo Alto and parts of Sunnyvale.

Starting today, if you call an Uber in Austin you can match with a self-driving Waymo vehicle. The launch in the Texas capital is part of an expanded partnership between the two tech companies. Waymo’s autonomous vehicles are already available on the Uber platform in Phoenix, and the companies plan to launch next in Atlanta.
