The streets of Wuhan, China, ground to an unexpected halt on Tuesday after a massive "system malfunction" caused over a hundred autonomous robotaxis to abruptly stop in the middle of traffic. The fleet of driverless cars, operated by Baidu under its Apollo Go service, was essentially frozen in place, reigniting safety concerns surrounding the readiness of autonomous vehicle technology.
According to local police, an initial investigation points to a widespread system failure as the culprit behind the simultaneous shutdowns. While authorities confirmed that all passengers were able to exit the stranded vehicles safely with no injuries reported, the mass malfunction was not without incident. Footage circulating on social media platforms documented streets paralyzed by the stalled cars, with at least one video appearing to show a highway collision resulting from the sudden stop.
Baidu has not yet responded to requests for comment regarding the outage, and police have stated that a deeper investigation into the root cause is still underway.
The Apollo Go service is one of the most prominent driverless taxi operations globally, operating primarily across dozens of Chinese cities. The tech giant has ambitious international expansion plans; recently, Baidu forged partnerships with ride-hailing heavyweights Uber and Lyft to bring Apollo Go vehicles to the UK, with pilot programs slated to begin in 2026 pending regulatory approval.
However, incidents like the gridlock in Wuhan highlight the unique and unpredictable hurdles facing the widespread adoption of autonomous transport. Jack Stilgoe, a professor of science and technology policy at University College London, emphasized that while AI-piloted cars might statistically out-perform human drivers, their failures present an entirely different set of hazards.
"While driverless tech may be safer on average, it can still go wrong in completely new ways," Stilgoe noted. "If we're going to make good choices about this technology, we need to understand entirely new types of risk."
Tuesday's event is just the latest in a series of technical blunders plaguing the global robotaxi industry. A recent power outage in San Francisco similarly crippled the city's Waymo taxi fleet, resulting in massive traffic bottlenecks. Meanwhile, another Apollo Go vehicle made headlines months prior when it inadvertently drove into an active construction pit in Chongqing while carrying a passenger.
