In February, Ford announced a $1 billion investment in Pittsburgh startup Argo AI, headed by CEO Bryan Salesky and COO Peter Rander, who both previously worked at Carnegie Mellon University’s National Robotics Engineering Center and led self-driving vehicle work at Google and Uber, respectively. The company has since announced a Strip District headquarters. That means Pittsburgh is up to four companies doing research and development on self-driving cars: Carnegie Mellon University, Ford/Argo AI, Uber and Delphi, whose cars you might not even know you’re driving next to. Mayor Bill Peduto made it clear in an interview with The Incline that’s the way he likes it — having multiple companies doing research, development and manufacturing here. “That’s always been the goal.”
