Since the system does not rely on a variety of sensors and a complicated symphony of factors, vehicles could technically navigate challenging circumstances as they emerge. This definitely seemed to be the case in San Francisco.  </p>    <figure><div> <blockquote><div lang="en" dir="ltr"><p>FSD is trained on billions of real-world miles, including power outages </p><p> @edgecase411 pic.twitter.com/JrFsyqK0Cn</p></div>— Tesla AI (@Tesla_AI) December 21, 2025</blockquote> </div></figure>    <figure><div> <blockquote><p lang="en" dir="ltr">Tesla Robotaxis were unaffected by the SF power outage https://t.co/uaYlhcSx25</p>— Elon Musk (@elonmusk) December 21, 2025</blockquote> </div></figure>    <h2><strong>Waymo’s blackout struggles</strong></h2>    <p>Waymo faced scrutiny after multiple self-driving Jaguar I-PACE taxis stopped functioning during the blackout, blocking lanes, causing traffic jams, and requiring manual retrieval.

While the failure of the utility infrastructure was significant, we are committed to ensuring our technology adjusts to traffic flow during such events,” the Waymo spokesperson stated, adding that it is “focused on rapidly integrating the lessons learned from this event, and are committed to earning and maintaining the trust of the communities we serve every day.”</p> <p>The post Tesla quietly flexes FSD’s reliability amid Waymo blackout in San Francisco appeared first on TESLARATI.</p></div>
