As Robotaxis Expand, Sleeping Passengers Are Straining City Emergency Resources

Summary

Robotaxi services operated by Waymo (Alphabet) and other autonomous vehicle companies are encountering an unexpected operational challenge: passengers falling asleep during rides and triggering emergency 911 calls. The phenomenon has become common enough that Austin police and firefighters have coined the term "sleepers" to describe these incidents, with Waymo recording 99 such calls in its first nine months of service in Texas. When remote operators monitoring the vehicles cannot rouse sleeping passengers through speakers and cameras, company protocols typically require them to call 911, forcing first responders to treat each case as a potential medical emergency.

The scope of human behavior challenges extends far beyond sleeping passengers. Riders are vomiting, spilling drinks, dropping food, experiencing medical emergencies, and even giving birth in the vehicles. Some passengers stumble out and forget to close doors, forcing companies to hire gig workers to secure the vehicles. In Austin alone, only about 3% of sleep-related emergency calls actually required hospital transport, meaning city resources are being heavily diverted from genuinely critical situations. Fire Chief Roger Patterson of Austin-Travis County Emergency Medical Services told city council that these calls are "very resource-heavy" while providing minimal actual medical benefit.

The operational failures extend beyond passenger behavior. The National Highway Traffic Safety Administration recently sent a letter to autonomous driving companies citing incidents where vehicles drove through emergency scenes, ignored flares and traffic cones, and obstructed ambulances. In San Francisco, more than 60 Waymos had to be manually moved after a blackout left them paralyzed on city streets, blocking emergency responders. Fire chiefs and emergency management officials are calling for standardized procedures across the industry, warning that without coordinated solutions, municipalities are essentially subsidizing the research and development of autonomous vehicles while absorbing the operational costs.

• Beyond sleeping passengers, robotaxis are facing issues with emergency scene obstruction, traffic blocking after system failures, and inadequate passenger management at destinations
• NHTSA and fire officials warn that cities are subsidizing autonomous vehicle operations while companies externalize operational costs and safety responsibilities to municipal governments

Editorial Opinion

The robotaxi industry has achieved impressive technical progress in autonomous driving, but the gap between engineering challenges and real-world operational chaos is widening faster than companies anticipated. When a technology shifts from carefully controlled pilot programs to city-scale deployment, the messiness of actual human behavior becomes impossible to automate away, yet companies continue to design systems that assume it will be. Without solving these fundamental operational problems—and without companies bearing the true cost of their solutions—robotaxis risk becoming a subsidy from taxpayers to tech giants, while first responders become unpaid quality-control testers.
