From press release:

“Just fifteen months after our first fully driverless ride, I’m thrilled to announce one of our biggest milestones yet: Cruise has completed one million fully driverless miles. Just about every mile we’ve logged has been packed with complex scenarios that have set Cruise up for rapid scale. And all of these miles were collected with our all-electric, renewable-powered fleet offsetting a total of 684 metric tons of CO2 emissions over the course of these million miles. The dense, often chaotic, streets of San Francisco have about 19,000 people per mile and give our fleet mountains of information-rich data to learn from.”
