Hundreds of Baidu's Apollo Go self-driving taxis in Wuhan, China, suddenly stopped working in the middle of traffic, stranding passengers for hours and causing accidents. The mass shutdown revealed that Baidu's robotaxis are linked under centralized control, posing a single point of failure and raising national security concerns about the ability to remotely disable an entire fleet.

Why it matters

This incident highlights the risks of over-reliance on centralized control systems for autonomous vehicle fleets. If a technical issue or malicious hack were to take down the central command, it could lead to widespread disruption and potential safety hazards. It also raises questions about the level of control governments may have over these systems, especially in authoritarian regimes like China.

The details

According to reports, dozens of Baidu's Apollo Go robotaxis suddenly stopped working on the roads in Wuhan, with some vehicles stranded on busy highways for over an hour. The mass shutdown caused crashes and left passengers trapped inside the cars. The incident revealed that Baidu's self-driving cars are linked to a centralized control system, rather than operating independently, which allowed the entire fleet to be disabled at once.

The players

Baidu

A Chinese technology company that operates the Apollo Go self-driving taxi service, which has a fleet of over 250,000 vehicles performing 250,000 rides per week as of late 2025.

Apollo Go

Baidu's self-driving car initiative, which uses a four-seater vehicle equipped with LiDAR, radar, ultrasonic sensors, and 12 cameras, and is capable of Level 4 autonomy.

What they’re saying

“Dozens of robotaxis by Baidu stopped on the road in Wuhan, causing crashes on highways and trapping passengers in the cars—some for more than an hour. One passenger told me it took her 30 minutes to even connect to a customer representative.”

What’s next

Regulators will likely scrutinize the software and control systems of autonomous vehicle fleets more closely to ensure there are safeguards against single points of failure and centralized control vulnerabilities.

The takeaway

This incident in China serves as a wake-up call for self-driving car makers and governments about the risks of over-reliance on centralized control systems for autonomous vehicle fleets. It highlights the need for robust fail-safes and decentralized architectures to prevent widespread disruptions and potential safety hazards.
