Amazon is gearing up to make as 10,000 robotaxis annually at a sprawling plant near Silicon Valley as it prepares to challenge self-driving cab leader Waymo.

The 220,000-square-foot factory is located in Hayward, California near its Foster City headquarters. This is Zoox’s second production facility in the Bay Area, adding to the assembly warehouse in nearby Fremont.

Amazon.com Inc.’s Zoox autonomous driving unit opened a robotaxi production facility in California in the latest move by a deep-pocketed tech company to expand the nascent industry.
