Can someone please teach Uber’s self-driving cars to read road signs?

Uber’s self-driving cars are marvels of modern technology. Unfortunately, they also don’t seem to know what a one-way street looks like. A video posted to Facebook shows one of Uber’s autonomous Ford Fusions undergoing testing in Pittsburgh. By “undergoing testing,” I really mean making a turn down a one-way road, before the human realised the mistake and made a large and embarrassing U-turn in the intersection.
