The proposal comes the same week Carnegie Mellon University made headlines with a driverless Cadillac SRX. The 2011 car modified by university engineers successfully transported a Pennsylvania congressman 33 miles to the Pittsburgh International Airport last week. Development for the vehicle, which uses radar, laser rangefinders and infrared cameras to detect traffic, started in 2008 after Carnegie Mellon won $2 million in a competition hosted by the U.S. Defense Advanced Research Projects Agency.
