A growing body of evidence is challenging the promise of seamless autonomous mobility. Recent incidents suggest that robotaxis may introduce new risks, especially on high-speed roads.

In early April 2026, more than 100 driverless robotaxis operated by Baidu suddenly stopped on busy roads in Wuhan, China. Vehicles stalled in live traffic. The incident left passengers stranded for up to 90 minutes on elevated highways.

Authorities attributed the disruption to a “system malfunction.” Several cars halted in middle lanes. This created immediate congestion and safety risks. In at least one case, another vehicle rear-ended a stationary robotaxi on a highway.

Videos shared online showed rows of immobilized vehicles. Traffic flow was disrupted across key corridors. Some passengers exited vehicles themselves, despite the danger from passing traffic.

The scale of the outage raises fresh questions. Wuhan hosts over 500 robotaxis, and reports suggest a significant portion failed at the same time.

Experts say such failures expose a critical vulnerability. Autonomous systems rely heavily on software stability. When that fails, risks escalate quickly. “System-wide outages can create cascading traffic hazards,” analysts note, pointing to the lack of immediate human intervention.

The incident is not isolated. In the United States, regulators have already launched investigations into self-driving systems. In one case, a robotaxi struck a child and triggered federal scrutiny.

Crash data also paints a mixed picture. Over 5,200 autonomous vehicle incidents have been reported in the U.S. since 2019. Around 7.4% involved injuries, while 1.2% were fatal.

At the same time, companies argue that long-term safety gains remain possible. Some industry studies suggest robotaxis could reduce accident rates compared to human drivers. However, these benefits depend on system reliability and real-world performance.

Still, the gap between promise and practice is evident. Autonomous fleets continue to face technical glitches, remote intervention needs, and regulatory scrutiny. The Wuhan incident highlights a simple reality. When driverless systems fail, there is no human fallback. The consequences are immediate and visible.

For cities planning to integrate robotaxis, the lesson is clear. Technology alone cannot guarantee safety. Cities must enforce strong oversight, build redundancy systems, and deploy rapid-response mechanisms before they can trust large-scale rollout.
