#1. Detecting road signs and traffic lights. It would be incredibly expensive to outfit every street in America with radio transmitters to tell self-driving cars the proper speed limit. Not to mention this huge project would be impractical: Why should the government spend billions just so lazy people can have "self-driving cars"? Road signs couldn't be programmed directly into the car itself, like in the OnStar system, either because of how they frequently change (I.E. during construction). Plus you can't
really detect traffic lights.
#2. I don't believe we have the kind of optics to be able to always accurately distinguish between various objects on the road, certainly not good enough to accurately track movement. It was a real challenge for us to develop a UGV which could even move through a static obstacle course... That's worlds away from ever building one that could detect the color of traffic lights, distinguish between bicyclists, autos, pedestrians and animals, and be able to move accordingly.
I think it will be a long, long time before we ever see a self-driving car, if ever, for two main reasons:The 39-year-old Stanford professor of electrical engineering is the world's most successful manufacturer of self-driving vehicles: He and his graduate students built Stanley, the first car to complete the DARPA Grand Challenge, a 131-mile robot car race across the desert near Las Vegas organized by the research arm of the Pentagon.
That historic success in 2005 netted Thrun a $2 million prize. He reinvested some of it in an even more intelligent Stanley, which will be unveiled at the next iteration of the robot car contest - one that takes place on city streets. Obstacles include stop signs, lights, and cars driven by humans.
