Editorial standard

Every number traces back to a source.

We do not estimate, predict, or invent figures. Each statistic published on AutoIndex24 is computed by a deterministic Python analyst against records from the National Highway Traffic Safety Administration, the Environmental Protection Agency, and bi-weekly aggregator inventory observations.

Narrative is added afterwards by an editorial layer that is explicitly forbidden from arithmetic. A separate validator re-extracts every numeric claim from prose and confirms it against the analyst’s findings before publication.
