Anyone with even a passing interest in AI or robotics is aware of the DARPA Grand Challenge  -  the military sponsored autonomus vehicle challenge. Tomorrow night (March 28th at 8 p.m.) the PBS show Nova will focus on this race in "The Great Robot Race". This is true "must see TV" for the geek in all of us. It's amazing the progress that has been made in the 2 short years that this challenge has existed.
