A Waymo driverless taxi has caused traffic to back up on a busy road in Austin, Texas, after appearing to be unable to navigate a puddle. This incident highlights the ongoing challenges that autonomous vehicles face in real-world conditions.

The incident comes just months before Waymo’s planned launch in the UK, which will see the world’s leading robotaxi service begin operations on the streets of London. The event has raised questions about the readiness of self-driving technology for more complex urban environments.

Footage of the stuck autonomous cab, shared by local outlet Fox 7 Austin, shows other cars passing through the puddle easily on the two-lane boulevard. The contrast between human drivers and the autonomous vehicle’s inability to handle a simple obstacle has sparked discussions about the limitations of current AI systems.

Another video from Austin news channel KXAN shows two Waymo vehicles drive into a larger puddle in the city before both stopping, forcing other drivers to navigate around them. These incidents have drawn attention to the need for improved sensor technology and decision-making algorithms in autonomous vehicles.

Waymo, a division of Google’s parent company Alphabet, currently operates a fleet of around 1,500 self-driving cars in five US cities. The company first announced that it would be expanding operations to London last November, with the first driverless rides expected in September.

“Waymo is making roads safer and transportation more accessible where we operate,” Waymo chief executive Tekedra Mawakana said at the time. “We’ve demonstrated how to responsibly scale fully autonomous ride-hailing, and we can’t wait to expand the benefits of our technology to the United Kingdom.”

UK secretary of state for transport, Heidi Alexander, said the move would “increase accessible transport options alongside bringing jobs, investment, and opportunities.” This expansion represents a major step forward for the autonomous vehicle industry, but also raises concerns about safety and regulation.

The latest traffic disruption in Austin follows thousands of other incidents involving self-driving cars, dozens of which have resulted in fatalities. These events have prompted increased scrutiny from regulators and the public alike.

The US National Highway Traffic Safety Administration has logged more than 5,000 autonomous vehicle accidents, with DMV logs tracking more than 50 collision reports involving autonomous vehicles since the start of the year in California alone. These numbers underscore the ongoing challenges that come with integrating self-driving technology into everyday traffic.

A 2025 report from market research firm IDTechEx warned that regulatory challenges and technical difficulties still remained in the autonomous taxi space. “Robotaxis are still in an extremely nascent stage,” the report noted. “As companies look to scale up to tens of thousands to potentially millions, any small error or delay could prove extremely dangerous.”

The Independent has reached out to Waymo for comment about the latest incident. While the company has not yet responded, the incident has reignited debates about the readiness of autonomous vehicles for widespread use.

The Independent has always had a global perspective. Built on a firm foundation of superb international reporting and analysis, The Independent now enjoys a reach that was inconceivable when it was launched as an upstart player in the British news industry. For the first time since the end of the Second World War, and across the world, pluralism, reason, a progressive and humanitarian agenda, and internationalism – Independent values – are under threat. Yet we, The Independent, continue to grow.
