According to SawyerMerritt on X, Waymo’s robotaxi fleet has surpassed 200 million fully autonomous miles, averaging about 448,000 miles per day since crossing 100 million miles in July 2025. As reported by SawyerMerritt, this rapid ramp underscores accelerated deployment in Phoenix, San Francisco, Los Angeles, and Austin, creating larger real‑world datasets that improve perception, planning, and edge‑case handling via continuous learning. According to SawyerMerritt, the sustained high‑mileage operations strengthen the business case for autonomous ride‑hailing by lowering cost per mile and supporting expansion into airport routes and late‑night service windows. As cited by SawyerMerritt, the scale also enables more robust safety benchmarking and reliability metrics, which enterprise partners and regulators require for service approvals and insurance underwriting.
