Waymo and Zoox Test-Driver Injuries Renew Robotaxi Safety Concerns

The report said test drivers experienced sprains and whiplash from sudden stopping and other mistakes while training autonomous vehicles around major cities. TechCrunch noted that the dataset is somewhat incomplete, largely because of the narrowness of OSHA's reporting mandates. Inside sources said injuries continued to occur at Zoox throughout 2026, while little is known about the results of Waymo's more up-to-date tests.

The findings add to a broader debate over autonomous vehicle safety. Autonomous car manufacturers have long claimed that self-driving vehicles would reduce traffic accidents. According to a report by the Insurance Institute for Highway Safety, Google's Waymo robotaxis were involved in roughly 65 percent fewer car crashes than human drivers last year. Waymo's own internal statistics claim that autonomous vehicles reduce accidents with serious injuries by 94 percent. Some critics say more testing is needed before those safety gains can be meaningfully certified.

Other data points have raised questions about the immediate feasibility of self-driving vehicles. Tesla's robotaxis recorded more accidents than their human counterparts during their rollout in Austin, Texas. News reports have also described autonomous vehicles plowing over traffic barriers, swerving into oncoming traffic, running red lights and driving into police standoffs. Some experts are concerned that such issues are likely to become more pronounced as the technology spreads, even if they occur relatively infrequently.

Autonomous vehicles struggle when road conditions become uncertain. In July 2026, Amazon's Zoox recalled over a hundred vehicles because they failed to identify smoke, following an incident in which a software glitch caused a vehicle to drive into an active emergency. A few months earlier, Waymo issued a similar recall after several taxis drove into flooded streets. Tesla, which recently launched its Cybercab robotaxi service, faced a federal probe over its self-driving software's struggles in reduced-visibility environments. Other examples include a Waymo recall for driving into closed roads and construction zones, the breaking of school bus safety regulations, and interference with first responders.

One of the most dangerous safety issues is autonomous vehicles' tendency to make sudden stops. According to TechCrunch, brake jabs were the most common cause of injury for AV testers, often caused by phantom debris. A report by researchers at the University of California Irvine further underscored the issue, noting that AVs often make dangerous stops when detecting harmless objects on the side of the road. Tesla faced a four-year-long NHTSA probe over phantom braking issues. Software glitches can also cause robotaxis to suddenly stop in traffic. Zoox contractors told TechCrunch that the company's software systems sometimes shut down, causing a sudden and dangerous stop.

System malfunctions and situational factors, such as power outages, can also cause a robotaxi to block traffic. In Wuhan, China, a system malfunction caused at least 100 robotaxis to stop in the middle of the road. Similar traffic congestion has occurred in San Antonio, Los Angeles, San Francisco and Atlanta, among other places.

The technology remains far from infallible, and passengers should approach an autonomous ride with caution and stay alert for warning signs. Erratic behavior such as unpredictable swerving, unreasonable speeds, breaking traffic laws and sudden braking are obvious red flags. More subtle issues, including unnecessarily complex routes, missed stops, and technical glitches with an app or car display screen, may also indicate potential software mishaps. Most robotaxis allow users to end their rides if they detect a problem. Waymo, for example, provides a Pull Over command in its phone application and in-car display; when pressed, the robodriver will navigate to a safe stopping place.

Editor's Summary A September 2026 TechCrunch report based on OSHA data says Waymo and Zoox caused dozens of test-driver injuries during robotaxi training, adding to existing scrutiny of autonomous vehicle safety. Waymo and others cite lower crash and serious-injury rates, while recalls, probes and traffic-blocking incidents show the technology still faces operational failures. Passengers are advised to watch for erratic driving, missed stops and software glitches, and to use ride-ending or pull-over functions when needed.
