A system malfunction caused at least a hundred self-driving robotaxis in Wuhan, China, to stop in the middle of traffic, stranding riders for hours on roadways.

According to the Guardian, local authorities in Wuhan began receiving calls from riders on the night of March 31, reporting that robotaxis operated by Chinese internet service Baidu had stalled in traffic. The exact number of cars involved remains unclear, and police are still working to determine the reason behind the malfunction.

This marks the second incident involving Baidu's robotaxis in a matter of months, after Zhuzhou, China, suspended the company's operations when an autonomous vehicle made by Baidu ran over two pedestrians in December of last year. Months before that, an Apollo Go robotaxi carrying a rider fell into a construction pit in Chongqing.

Baidu's Apollo Go driverless taxi service operates in dozens of cities, primarily in China. Ridesharing services Uber and Lyft both also announced partnerships with Baidu in December 2025 to test Apollo Go vehicles on roads in the United Kingdom sometime in 2026. Baidu reported 3.4 million driverless rides in the fourth quarter of 2025, and saw its total rides rise by more than 200% year-over-year.
