Nissan plans to put driverless cars on streets by 2020

Nissan is working toward technology to put truly driverless cars on the streets of Tokyo by 2020. The project's goal is driverless commercial vehicles that could deliver packages or transport people on short trips. Work will begin this year with DeNA, a Japanese Internet company, and initial trials will take place in designated driverless car test zones in Japan. The 2020 goal is aggressive, but Nissan probably has the Tokyo Olympics in mind. Many Japanese companies have similar projects to wow Olympic visitors and help the country put its best foot forward.
