As Waymo and its robotaxi rivals race to add cities and rides, the messier side of that expansion is surfacing. In Dallas, a pedestrian was struck by two vehicles, one a Waymo car; nationally, reporting shows robotaxi operators are hitting unexpected snags — construction zones, emergency scenes — faster than they can patch them. A comparison of two major U.S. operators found stark safety gaps, with one logging 14 crashes in 800,000 miles despite a human safety driver up front. Meanwhile, a federal judge in San Francisco refused to let Waymo keep running its cars overnight while it appeals a regulatory ban, underscoring how far ahead of oversight the technology is moving.
