The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.
Stated as firm, per waymo.com's post dated November 12, 2025: "as we begin welcoming riders to use Waymo on freeways across the San Francisco Bay Area, Phoenix, and Los Angeles" and "Today, we're also opening access across the entire Peninsula"; the SF Standard[3]: "Waymo will begin operating on Bay Area freeways on Wednesday" (12 Nov).
ABC7, later: "Waymo[1] began driving on Bay Area freeways in November" and "In December, San Jose Mineta International Airport became the first in California to allow passengers to be dropped off via Waymo."
SF Standard, same day: "Waymo[1] will begin operating on Bay Area freeways on Wednesday and is extending its service to San José"; a unified zone of more than 260 square miles; freeways 101 and 280; early-access riders first; SFO not yet in the service area.
SFist: lists the Peninsula cities added (San Bruno, San Mateo, San Carlos, Redwood City, Palo Alto, Mountain View, San José) and says SFO rides were still to come.
Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most.
