Led by CEO Aicha Evans, Zoox is aiming to offer free rides to more members of the public early next year, before opening up to paying customers and the general public.

The service will start in Las Vegas and expand to San Francisco, the company told CNBC. It will begin with an early rider program called Zoox Explorers, allowing select users to ride in a Zoox for free and provide feedback.

With its robotaxis currently on public roads in Las Vegas, San Francisco and Foster City, this summer, Zoox also began testing in Austin and Miami, where its test fleet is still driving.
