Massive San Francisco power outage leaves 130k in the dark, self-driving cars stalled

San Francisco plunged into darkness when nearly 30 percent of the city was struck by a power outage, which brought vital transportation, such as self-driving cars, to a grinding halt on Saturday night. Over 130,000 houses and businesses were left in the dark, largely in the northwest part of San Francisco, including the Richmond, Sunset, Presidio, and Golden Gate Park sections, officials said on Saturday.
