Alphabet-owned Waymo said its robotaxis have driven more than 100 million miles without a human at the wheel, doubling the total distance in roughly six months. “Years of methodical progress are now accelerating into rapid, responsible scaling,” Chief Product Officer Saswat Panigrahi said, noting the fleet had logged only 71 million miles as recently as March. The milestone coincides with a major service expansion in Austin, where Waymo on Thursday more than doubled its operating area—from 37 to 90 square miles—and made fully driverless rides available city-wide through the Uber app. The company already has more than 100 vehicles deployed in the Texas capital and says the number will grow to several hundred. Waymo’s push intensifies competition with Tesla, which launched a supervised robotaxi pilot in Austin last month and recently widened its own coverage map. Waymo, which operates about 1,500 vehicles across Phoenix, San Francisco, Los Angeles, Austin and Atlanta, has completed over 10 million paid trips and is seeking permits for additional U.S. cities as the race to commercialize autonomous ride-hailing accelerates.
