A technical glitch left hundreds of Baidu’s self-driving taxis stranded on Chinese highways, causing significant disruption to passengers. A student in Wuhan described being stuck for over an hour before finally exiting the vehicle with friends.

Passengers reported challenges reaching customer support and even had to force open their doors as they waited. Meanwhile, other incidents of near-misses and collisions highlighted the risks involved until full automation is perfected.

The incident has sparked online complaints about Baidu’s response times and service quality. Local authorities have stated a system malfunction was likely but are still investigating the extent of the problem.

As autonomous vehicle technology expands, the reliability of these systems will be crucial in ensuring public safety and trust. Until then, passengers might want to keep their phones handy—and their car keys too.
