Pittsburgh sours on Uber's driverless car experiment

Nine months after Uber rolled out its self-driving car trials in Pittsburgh, the relationship is deteriorating, the New York Times reports.

Why it matters: Self-driving car companies are forming partnerships with cities that will allow them to test their vehicles on their streets. It's a high-risk, high-reward proposition for city leaders.

Pittsburgh Mayor Bill Peduto told The Washington Post this fall, "Is there going to be an accident in a robot car? Yes there is. But the greater goal is to make our streets safer in the long term. We have to start at some point and we can't wait for regulation to catch up with innovation."
