Tesla's accelerating driverless mileage in Austin suggests its technology is shifting from gradual progress to a rapid rollout. A chart from RtaxiTracker, shared by Nic Cruz Patane, puts Tesla at 438,000 miles in the week to October 18, versus Waymo's 406,000 weekly average in Q2 2026; Waymo's figures lag Tesla's, so these are not same-week readings. x.com
