It’s been just over a year since Waymo rolled out its partnership with Uber, and its presence has rapidly expanded across Austin. There are now about 300 of the sleek white vehicles with black spinning tops driving around city streets, a level of ubiquity the company asserts is improving safety for pedestrians and drivers. Not everyone is sold. Some city leaders say the vehicles can, at times, hinder public safety. In the wake of several high-profile incidents over the past 12 months — including the recent death of a beloved duck, an incident in which a Waymo vehicle blocked an ambulance responding to the shooting at Buford’s Backyard Beer Garden and reports of autonomous vehicles unsafely passing school buses — skepticism is growing about whether the technology is ready for widespread use. City leaders also say the companies can be opaque about how their systems operate.
