A U.S. safety group said Japanese and German automakers dominated the list of the safest vehicles on American roads, in part by adding advanced technology to prevent frontal collisions. The Insurance Institute for Highway Safety, an industry funded group that prods automakers into building safer cars by awarding influential ratings, said Thursday that Toyota Motor Corp. topped the list of 48 Top Safety Pick+ of 2016 with 9 winners, which included the Camry, the best-selling U.S. car.
