Human beings and their unpredictability continue to be the cause of most autonomous vehicle accidents. As a surprising statistic, nearly all of the accidents involving an autonomous vehicle thus far have proven to be the fault of the human. It's somewhat incredible considering the field is barely a decade old, Stanley (pdf) only won the DARPA Grand Challenge in 2006. Researchers looking into the current rash of accidents have basically determined the autonomous vehicles are having issues because they obey the laws and humans do not. Much like the though problem from a few years ago regarding how an AI should choose which fatality was the best choice, the new question is whether an autonomous vehicle should break the law in order to behave more safely with humans. The most frequently cited example is high speed merges onto highways where a legal speed will result in getting rear ended.
