Waymo LLC Collision — Sacaton, AZ, US — December 2022
What is observable from the evidence
No individually observed facts are recorded for this record; see its structured details and sources instead.
Automation status
Driving automation not engaged
Whether the driving-automation feature was engaged is a separate question from whether it caused the event.
System / software version
Not identified in the available sources.
Causal attribution
Undetermined
The available evidence does not establish a cause. Involvement of a driving-automation system is not the same as its being a cause.
Subject vehicle was changing lanes under manual control (automation not engaged). Existing causation vocabulary has no category for "subject vehicle's own human driver" distinct from automation vs. other-party — left conservative pending a rulebook decision (see Normalization Rulebook v1 §6, open question 1).
What remains unknown
- Contributing reports disagree on crash interaction counterpart (Heavy Truck / Other, see Narrative) — left unresolved for curator review.
