A power outage in San Francisco has reportedly "bricked" multiple Waymo autonomous vehicles, highlighting a potential vulnerability in self-driving technology's reliance on consistent infrastructure. This incident could negatively impact investor sentiment for companies heavily invested in autonomous driving, such as Alphabet (GOOGL), which owns Waymo, due to concerns about operational reliability and scalability in real-world conditions. Investors should monitor how Waymo addresses these infrastructure dependencies and potential impacts on future deployment plans.
