What is observable from the evidence

No individually observed facts are recorded for this record; see its structured details and sources instead.

Automation status

Unknown

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.

No structured or narrative evidence directly supports a more specific causation category; conservative default applied per Normalization Rulebook v1.

What remains unknown

  • Contributing reports disagree on crash interaction counterpart (Other Fixed Object / Pole / Tree) — left unresolved for curator review.
  • Contributing reports disagree on subject vehicle precrash movement (Changing Lanes / Unknown) — left unresolved for curator review.
  • Contributing reports grouped under this NHTSA Same Incident ID contain materially inconsistent descriptions across 2 event-shape fields (crash_interaction_counterpart, subject_vehicle_precrash_movement). WBA preserves this source-record inconsistency without determining which description is correct or whether the source grouping represents one or multiple physical events.
