Japanese PM Shinzo Abe tests self-driving cars Technology News World "World's best": Shinzo Abe passes the Diet building in a self-driving Nissan on Saturday. Tokyo: Japanese Prime Minister Shinzo Abe has taken a ride in several self-driving vehicles on Tokyo's public roads, showcasing the technology before the Tokyo Motor Show. Mr Abe tried auto-piloting vehicles from Toyota, Honda and Nissan on the roads around Japan's Diet building on Saturday, as international car makers compete with Google and other technology firms to develop new types of cars with the goal of reducing accidents by eradicating human error. "I felt with my body that the Japanese technology is the world's best," Mr Abe said after riding the vehicles. Car makers have previously tested self-driving vehicles on highways without pedestrians. This month's Tokyo Motor Show will feature self-driving technology, as well as electric vehicles and other models. Mr Abe has pledged to help advance auto-piloting technology as part of his economic policy.
