NHTSA probes whether Waymo's school bus recall fix actually worked
NHTSA has opened a formal investigation into Waymo's software recall meant to stop its robotaxis from illegally passing stopped school buses with extended stop arms. Waymo issued a software fix in mid-November and a formal voluntary recall in December, but the agency says most reported school bus passing incidents occurred after those dates, including one flagged by the NTSB in mid-January.
