Waymo's passenger miles improved from 36% to 56% of total vehicle miles between August 2023 and December 2025\. The shift reflects reduced empty repositioning drives and improved dispatch efficiency—the operational bottlenecks that have constrained autonomous taxi economics. At 56% utilization, Waymo approaches the 50% threshold where robotaxi unit economics become competitive with traditional ride-hailing, which typically operates at 40-45%. The business model is moving toward viability as scale increases ride-request density relative to vehicle supply.
