Boris Johnson for Mayor of... San Francisco?

Eric Horvitz is the president of the Association for the Advancement of Artificial Intelligence, as well as being an AI researcher at Microsoft. When stuck in traffic one day in Seattle, he asked his nav system to reroute him via side streets, and the result was worse than being stuck on the highway. That incident turned into four years of research and data collection on traffic patterns to create the Clearflow traffic avoidance system for Microsoft's web portal-based Live Search Maps.
