schwit1 sends in a story from Bloomberg pointing out that the rigid adherence to traffic laws and overcautious programming have caused self-driving cars to rack up a crash rate twice that of an average human driver. "This may sound like the right way to program a robot to drive a car, but good luck trying to merge onto a chaotic, jam-packed highway with traffic flying along well above the speed limit. It tends not to work out well. As the accidents have piled up — all minor scrape-ups for now — the arguments among programmers at places like Google and Carnegie Mellon University are heating up: Should they teach the cars how to commit infractions from time to time to stay out of trouble?" While the autonomous vehicles aren't at fault in these crashes, their relative unpredictability on the road are nonetheless leading to more accidents than expected.
