On Thursday, a J on a rainy evening in San Francisco’s Height neighborhood. Luckily, the injuries to the pedestrian don’t appear to be major, and Waymo has stated that the car was being driven by a normal, moist human as opposed to being under the control of Waymo’s self-driving system.

of a witness, though the actual impact is off-camera. The video does show the environment just prior to the crash, and there are a number of challenging factors at work on the neighborhood street, including rain and a wet road, along with a parked police car with flashing lights and reflections, which does create a challenging visual environment for anyone, human or machine.

The Waymo car does seem to be driving sort of fast for that street and conditions in the video, but that’s just me looking at the video, and in no way should be taken conclusively, as I do not have speed information at this time.

You can see the safety driver’s hands on the wheel in the video, and while that doesn’t necessarily mean the safety driver was in control, it does at least show they weren’t texting or blatantly not paying attention.

Waymo PR representative responded to a tweet about the accident, stating that the car was under human control at the time:

Investigators will likely confirm or deny this, but based on the poor weather, I wouldn’t be surprised to find that the car was being human-driven. Of course, , which makes sense as automated vehicles will need to drive in all kinds of conditions, though does specify “behavioral competencies” of their safety drivers that includes

43 Detect and Respond to Unanticipated Weather or Lighting Conditions Outside of Vehicle’s Capability (e.g. rainstorm)

44 Detect and Respond to Unanticipated Lighting Conditions (e.g. power outages)

...both of which, weather and lighting conditions, appear to be factors in the conditions of this incident, and likely would have prompted a safety driver to take control.

Of course, humans make mistakes while driving, which is part of why anyone is bothering trying to figure out how to make machines do it at all, and these conditions could be challenging for people as well.

Waymo issued a generic-sounding statement saying:

“The trust and safety of the communities in which we drive

are paramount to us, and we will continue investigating this

incident in partnership with local authorities,”

...and they do seem to have contacted California’s DMV, and will file a crash report for evaluation.
