NHTSA launches probe into Tesla Cybercab deployment
The National Highway Traffic Safety Administration (NHTSA) opened an investigation into Tesla’s Cybercab deployment on September 4, 2026, mere hours after the company placed the first production units on public roads in Austin. This regulatory action follows a pattern of close federal scrutiny on new autonomous vehicle entrants, mirroring previous inquiries into other operators. The investigation will likely focus on the vehicle's self-certification process and initial performance data as it integrates into mixed traffic.
Waymo expands paid service to Denver, San Diego, and Tampa
On September 1, 2026, Waymo officially launched fully driverless paid rides in Denver, San Diego, and Tampa, increasing its operational footprint to 14 US cities. This expansion brings the total number of cities with Waymo service to 14, significantly broadening its market reach. The move comes as Waymo continues to scale toward its goal of 1 million weekly rides, currently sitting at over 500,000.
Zoox robotaxi involved in rear-end collision in Las Vegas
A driverless Zoox vehicle was struck from behind at an intersection in Las Vegas on September 7, 2026, just days after the company expanded operations to Harry Reid International Airport. The incident occurred at Decatur Boulevard and Russell Road, raising questions about the vehicle's interaction with human drivers in complex urban environments. While no injuries were reported, the crash adds to the safety data being monitored by regulators and the public as Zoox scales its commercial pilot program.
Tesla AI lead hints at 24/7 Robotaxi service soon
Tesla’s AI lead, Ashok Elluswamy, stated on September 6, 2026, that the company is "not far" from achieving 24-hour full-time operation for its Robotaxi service. This capability is expected to arrive "next month or so" once the next technology merge on the v15 plan is complete. If realized, this would allow Tesla to compete more directly with Waymo and other operators that already offer round-the-clock availability in their service areas.
Local view
In San Diego, local media reported high interest in Waymo’s launch, noting that Amazon’s Zoox also began testing fleet operations in the city during September. The San Diego Union-Tribune highlighted that while Waymo started picking up passengers immediately, Zoox’s entry was initially limited to testing phases. Residents expressed mixed reactions, with some welcoming the new transport option and others expressing caution following recent national news about autonomous vehicle incidents.
Context & numbers
Waymo continues to lead in volume, reporting more than 500,000 weekly paid rides as of early September 2026, against a target of 1 million by year-end. The fleet size is estimated to be growing at a rate of 265 to 300 vehicles per month, which could support approximately 840,000 weekly rides by the fourth quarter if pace is maintained. In contrast, Tesla’s Cybercab deployment is in its earliest stages, with only a small number of vehicles currently under federal investigation in Austin.
On the radar
- Tesla v15 Update: Watch for the completion of the "v15 plan" tech merge, which Tesla claims will enable 24/7 Robotaxi operations within a month.
- Zoox Expansion: Following the Las Vegas incident, monitor any regulatory responses or changes to Zoox’s testing protocols in Nevada and other expanding markets like Houston and San Diego.
- Waymo Fleet Growth: Track weekly ride counts to see if Waymo maintains its trajectory toward 1 million weekly rides, which would require significant acceleration in fleet deployment.
