A Pennsylvania congressman caught a cutting-edge ride to the airport on Wednesday.
Rep. Bill Shuster, a Republican from Altoona, made a 33-mile trip from Cranberry Township to Pittsburgh International Airport at about 11 a.m. in a computer-operated car. 
The so-called driverless Cadillac SRX was designed by Carnegie Mellon University researchers who have been working on the project since 2008. The car uses inputs from radars, laser rangefinders, and infrared cameras to maneuver in traffic.
Shuster is the chairman of the House Transportation and Infrastructure Committee, and he was accompanied by Barry Schoch, secretary of the Pennsylvania Department of Transportation.
