Waymo co-CEO Dmitri Dolgov has issued a stark warning to artificial intelligence developers building robots and autonomous vehicles, urging them to abandon Silicon Valley’s traditional "break things" culture. Speaking at a Y Combinator interview released on Monday, Dolgov emphasized that unlike digital products where mistakes can be undone, failures in physical systems operating around people can cause irreversible harm, including loss of life. He proposed a new industry mantra: "Move fast and ship safely," arguing that safety must be embedded into models, training methods, and system architecture from the outset rather than added as an afterthought.

Dolgov’s comments carry significant weight given Waymo’s operational scale and recent regulatory challenges. The Alphabet Inc. subsidiary has logged more than 220 million rider-only miles and currently delivers more than 500,000 fully autonomous trips weekly. Research comparing 56.7 million of these miles with human benchmarks found statistically lower rates of injury-reported and airbag-deployment crashes. However, the company’s record is not without blemishes, highlighting the complexities of deploying physical AI at scale.

Operational Metrics and Safety Record

Waymo’s expansion demonstrates both the potential and the risks of autonomous technology. While safety studies support cautious commercial deployment, recent recalls and federal scrutiny underscore the need for continued testing.

In May, Waymo recalled nearly 3,800 robotaxis because software could send vehicles into flooded roads. This was followed by a recall of almost 3,900 vehicles after more than a dozen incidents where robotaxis entered closed freeway construction zones, leading to a temporary suspension of freeway service while updates were installed.

Regulatory Scrutiny and Industry Implications

Beyond recalls, Waymo faces ongoing federal scrutiny. The National Highway Traffic Safety Administration (NHTSA) warned autonomous-vehicle developers in July about a "clear pattern" of driverless vehicles entering emergency scenes, blocking first responders, or failing to respond correctly to lights, smoke, and traffic cones. NHTSA Administrator Jonathan Morrison stated in early July that any automated vehicle unable to interact safely with first responders presents a danger to the public.

Dolgov’s argument highlights a critical divergence in the AI sector. While chatbot mistakes typically require only another attempt, failures involving vehicles cost "human lives, not tokens." As physical AI expands beyond controlled environments, the industry must balance rapid innovation with rigorous safety protocols to prevent irreversible consequences.

San Francisco Mayor Daniel Lurie has demanded a stricter regulatory framework for autonomous vehicle operators following a gridlock incident involving Waymo robotaxis during the city’s Fourth of July fireworks show. The disruption occurred when more than 100,000 people gathered at the northern waterfront, leading to traffic congestion as dozens of driverless vehicles stalled in travel lanes and parking areas. The incident caused some robotaxis to run out of battery power while idling, blocking municipal shuttle buses and hindering emergency vehicle routes.

Operational Challenges

The event marks another operational challenge for the autonomous driving leader. Waymo recently recalled thousands of robotaxis over a software issue and suspended its services in the city following an outage at a Pacific Gas & Electric Co. Common Stock substation late last year. The company, along with Tesla and Zoox, did not immediately respond to requests for comment regarding the latest incident.

Call for Stricter Framework

In a letter to the California Secretary of Transportation, Lurie stated that California’s current regulatory framework does not adequately address how autonomous vehicles operate during major incidents. He urged state officials to implement stricter safety requirements. The mayor’s proposed framework seeks to grant local authorities more control, including the ability to mandate that companies move immobilized vehicles out of active lanes quickly and share real-time fleet data during major public events.

Regulatory Scrutiny

The National Highway Traffic Safety Administration (NHTSA) has also warned of an increasing number of incidents involving autonomous vehicles blocking first responders and law enforcement operations during incidents. The agency has demanded that companies issue a fix by the end of the month to address these concerns.
