Congressman hitches a ride in a stealthy self-driving Cadillac

Google’s not the only entity testing self-driving cars on actual US roads. Today, Bill Schuster (R-PA), the congressman who chairs the House Transportation and Infrastructure Committee, took a 33-mile trip in an autonomous vehicle built by Carnegie Mellon University and funded by General Motors. The 2011 Cadillac SRX ferried the Pennsylvania congressman from the town of Cranberry to Pittsburgh International Airport earlier this morning, while a cameraman broadcast his journey to the web.
The trick: unlike Google’s self-driving vehicles, the Cadillac doesn’t require a giant spinning array of lasers mounted on the roof.
