SAN FRANCISCO -- When Vita Shafiro, 51, and her daughter Mikhaela, 15, recently walked back to their downtown San Francisco hotel after sightseeing, an odd vehicle caught their eye.

She and her daughter returned the next day and rode a Zoox to the Ferry Building, a landmark on the San Francisco waterfront.

It cannot yet charge for a ride in San Francisco as it awaits state regulatory approval.

For now, Zoox offers only free demonstration rides in San Francisco, which began in November 2025.

Driverless car companies are still selling the very concept of a driverless taxi, he said.
