Real-world injury-crash reduction in limited cities is major for AV safety (tier 3). Attribution is to the full AV stack, not a public LLM. Peer-reviewed comparison plus NHTSA SGO inputs (0.70). Realization is paid rider-only service. Durability depends on continued operations. Follow-up ingest: added a follow-up source.

What happened

Comparisons used matched human-crash estimates from state and insurance data. Independent researchers have generally treated the direction of the result as credible while debating residual selection effects and exposure definitions. The stack is a specialized AV system, not a general LLM. Service remains geographically limited. Update (2026-09-22): Anthropic launches Claude Opus 5.5: Benchmarks, pricing, safety - Mashable.
