MIT Technology Review has an article titled Your Driverless Ride is Arriving, about the Uber self-driving car experiment in Pittsburgh. Uber is using Pittsburgh to test how well driverless cars can do in an urban environment. The articles author gives a detailed description of what it's like to ride in one of the test cars in Pittsburgh, and talks to CMU robotics faculty who are also working on the autonomous car concept. His conclusion: "Uber thinks its self-driving taxis could change the way millions of people get around. But autonomous vehicles aren’t anywhere near to being ready for the roads."
