Waymo is the first US firm to crack the robotaxi code, but the competition is heating up. On June 18, the Zoox branch of Amazon introduced its new factory in California, aiming for a launch of the service later this year in Las Vegas. That news was soon buried under the hype leading up to Tesla’s robotaxi unveiling in Austin on June 22. Despite the buildup, the error-filled Tesla event was a soft launch that barely missed faceplant territory, and CEO Elon Musk has made the task of selling the service much harder since then.
