Why this model scores 44.5
Capability reflects robust but geographically and operationally bounded physical driving rather than broad cognition. Autonomy is high because the system performs the complete dynamic driving task without an onboard fallback driver. Deployment reflects a paid public service with limited fleet and geography. Misuse is low because access, hardware, and operations are centralized. Control difficulty is moderate because physical operation carries safety risk but remains geofenced, remotely monitored, and fleet controlled.
News tied to Waymo Driver 4th generation
The model score of 44.5 rates this model's risk profile. The overall Doom Index of 66.8 measures the complete temporally weighted evidence record. These values answer different questions.
Each article's current Doom Index contribution is divided equally among the exact models named on that article. This prevents multi-model evidence from being claimed in full on several model pages. Model risk scores use a bounded temporal offset around their technical profile, but never feed back into the overall index.
