Provide recurring field audits using trained mystery riders who execute standardized trips across operating zones, including blind or visually impaired testers and scenarios involving blocked roads, ambiguous curbs, missed pickups, and lost property. Each engagement delivers reproducible evidence, severity-ranked findings, curb-location corrections, support transcripts, and retest results to the operator's safety and city-launch teams. The first version is a managed field service supported by lightweight trip logging and evidence-capture tools.

Autonomous ride services are expanding into unfamiliar neighborhoods while passenger experience defects increasingly involve physical curb conditions, accessibility, and real-time support rather than isolated app bugs. Independent field validation can be launched city by city without building vehicles or competing ride software.
