Nissan Carwings

The idea behind CarbonGage for Auto has taken hold in Japan. The Japanese government has awarded Nissan's Carwings Eco-drive navigation system program its Energy Conservation Prize. Eco-drive tracks fuel efficiency and charts personal performance, ranks the driver's performance against other Carwings members, gives tips on how to cut fuel consumption and then calculates how much money has been saved on gasoline over time. The system is currently offered only in Japan where it has been available since 2007. Carwings has an advantage in Japan due to the ability to use a nationwide database of real-time traffic conditions operated by the Japanese Transportation Ministry and police, however it can be reproduced here in the Americas, you just wait...
