Google may have another competitor hot on their heels for the title of leader in self-driving cars. At CEATEC, Nissan showed off a modified version of its Leaf called the NSC-2015. It has new self-parking technology built-in. This new technology works with a smartphone, and Nissan showed it off with a Samsung Galaxy S III.
I guess I can't really say this app will help you save those precious MPG on your car, but that is because it doesn't need that stuff we so deeply depend on called Gasoline -- or oil. Recently Nissan released an Android app just for the Nissan LEAF. From initially checking it out I want the car just based on how awesome the app is.
