Waymo had to rescue an autonomous van that was confused by safety cones

Programming a computer to understand and navigate roads designed for human drivers is hard. Rarely, however, do we get to see just how many things can go wrong when an autonomous vehicle encounters a situation it doesn't know how to tackle. A 35-minute video from Joel Johnson (via Autoblog), a YouTuber who shares clips of his trips with Waymo One in Arizona, offers a rare glimpse into a perfect storm of errors. About 12 minutes into the video, Johnson's car wants to turn right onto a multi-lane street. Unfortunately for Waymo Driver, the rightmost lane was closed, with construction cones marking the obstruction.
