No driver? No problem. Robotaxis eye San Francisco expansion

SAN FRANCISCO (AP) — Two trailblazing ride-hailing services are heading toward uncharted territory as they seek regulatory approval to transport passengers around the clock throughout one of the most densely populated U.S. cities in vehicles that will have no one sitting in the driver’s seat. If Cruise and Waymo reach their goal of winning regulatory approval before year’s end, San Francisco would become the first U.S. city with two totally driverless services competing against Uber, Lyft and traditional taxis. But the companies still must navigate around potential roadblocks, including complaints about their vehicles making unexpected, traffic-clogging stops that threaten to inconvenience other travelers and imperil public safety.
