According to the passage, which of the following is NOT the reason for the rise of overall fatalities in recent years?

参考解析：

细节理解题。根据第二段最后一句“Overall fatalities, however, have been rising as well in recent years as drivers deal with increasing distractions in their cars and Americans put more miles on their vehicles during the period of a strong economy and low gasoline prices.”可知，近几年来，由于司机们在开车时越来越分心，美国人在经济强劲和汽油价格低廉的时期增加了驾车里程，总的死亡人数也在上升。所以C项和D项正确；根据第三段第一句“Companies like Uber, General Motors Co. And Alphabet Inc. are developing driverless cars, partially motivated by the potential for fewer car accidents.”可知，一些公司在开发无人驾驶汽车，部分原因是想减少车祸，B项错误；根据第五段可知，酒后或吸毒开车也是造成人员伤亡的原因。故选B。
