Waymo Admits One of Their Robotaxi's Hit a Child in California, Says Accident Could've Been Worse

Waymo, the autonomous driving subsidiary of Alphabet, has confirmed that one of its self-driving vehicles struck a young pedestrian in California last week. In a blog post published on Wednesday, the company addressed the incident in Santa Monica, arguing that its technology significantly mitigated the severity of the collision compared to a human driver.

The admission comes as the National Highway Traffic Safety Administration (NHTSA) prepares to launch a formal investigation into the event, a move Waymo states it fully supports. Coincidentally, the accident occurred a month after the agency sent the company a letter announcing the conduct of a preliminary investigation stemming from multiple reports of Waymo vehicles failing to wait for stopped school buses with flashing lights.

The Incident in Santa Monica

According to Waymo's official statement, the collision occurred on Friday, 23 January, in Santa Monica. The company reported that a young pedestrian 'suddenly entered the roadway' from behind a large, stationary SUV, stepping directly into the path of the oncoming robotaxi.

Waymo's data indicates that the autonomous vehicle's sensors detected the individual the moment they emerged from behind the visual obstruction. The vehicle, marketed as the 'Waymo Driver', reportedly executed an emergency braking manoeuvre, decelerating from approximately 17 mph to under 6 mph at the moment of impact.

'Following contact, the pedestrian stood up immediately (and) walked to the sidewalk,' the company wrote in its transparency update. Emergency services were called to the scene, and the vehicle remained stationary until cleared by law enforcement.

The current medical condition of the child has not been publicly released beyond the detail that they were able to walk away from the collision.

AI vs. Human: The Safety Defence

In a move to defend the efficacy of its autonomous systems, Waymo released comparative data suggesting a human driver would have caused greater harm in the same scenario. The company cited its own peer-reviewed modelling, which calculated that a 'fully attentive human driver' would likely have struck the child at approximately 14 mph—more than double the speed at which the robotaxi made contact.

'This significant reduction in impact speed and severity is a demonstration of the material safety benefit of the Waymo Driver,' the blog entry asserted. This 'gap' between human reaction time and AI processing speed is central to the industry's argument that self-driving cars are safer than their human counterparts, despite high-profile accidents.

Regulatory Scrutiny Intensifies

The collision has triggered immediate federal attention. Waymo confirmed it voluntarily reported the incident to the NHTSA on the day it occurred. The federal regulator has since indicated it will open a probe into the crash.

This investigation adds to the growing scrutiny of autonomous vehicle operators in the United States, following a series of incidents involving rival companies such as Cruise and Tesla.

While Waymo has generally maintained a stronger safety record than some competitors, this event underscores the persistent challenges autonomous vehicles face in unpredictable urban environments, particularly involving vulnerable road users like children. The company reiterated its 'commitment to transparency' and promised full cooperation with federal investigators as the inquiry proceeds.
