Ghosn predicts autonomous cars on the roads by 2018, if laws allow

Things appear to be going well inside Nissan's autonomous vehicle development program. Until now, the automaker believed that self-driving cars would be ready for major markets like the US by 2020. However, Renault-Nissan CEO Carlos Ghosn is now speeding up that prediction to 2018 in some places, assuming that local laws are ready to accept the computer-controlled vehicles.
"The problem isn't technology, it's legislation, and the whole question of responsibility that goes with these cars moving around," said Ghosn in a speech in France recorded by Reuters. He predicted that the first sales could begin in France, Japan and the US by 2018 and expand elsewhere in 2020.
The alliance has been among the forefront of automakers working on self-driving cars. Nissan has an autonomous Leaf (pictured above) test car that is licensed to drive on Japanese roads. Renault showed off an version of its Zoe EV earlier this year called the Next Two, that could pilot itself at speeds up to 18 miles per hour, and that the company predicted would be ready by 2020.

This map reveals the cleanest vehicles based on location

Naysayers love to point out how dirty the electricity grid mix is when it comes to charging electric vehicles. Curmudgeons are eager to jump into any conversation about EVs to enlighten the lucky listeners about how plug-in cars contribute to pollution, sometimes even throwing in a dash of climate-change denial for good measure. (Thanks, buddy. Pray, tell me more about the plight of oppressed SUV owners.) Unless someone buys an EV just because they think they're cool (which, yeah, they often are), they probably have at least a passable understanding of their environmental pros and cons. As many EV owners are already aware, location has a lot to do with any particular plug-in car's carbon footprint. Still, there's always more to know, and knowledge is not a bad thing, especially if one uses it to do the right thing. That's why this handy-dandy map from Carnegie Mellon University is so interesting. CMU researchers have compiled information about the lifecycle greenhouse gas emissions of various EVs based on where they're charged, as compared to gasoline-powered vehicles. The researchers looked at the Nissan Leaf, Chevrolet Volt, and Prius Plug-In Hybrid versus the gasoline-dependent Toyota Prius hybrid and the stop-start-equipped Mazda3 with i-ELOOP and compared grams of CO2 emitted per mile. CMU takes into account the grid mix, ambient temperature, and driving patterns. CMU takes into account the grid mix based on county, as well as ambient temperature and driving patterns in terms of miles traveled on the highway or in the city. For instance, if you drive a Nissan Leaf in urban areas of California, Texas, or Florida, your carbon footprint is lower than it would be if you were driving a standard Toyota Prius. However, if you charge your Leaf in the Midwest or the South, for the most part, you've got a larger carbon footprint than the Prius. If you live in the rural Midwest, you'd probably even be better off driving a Mazda3. Throughout the country, the Chevrolet Volt has a larger carbon footprint than the Toyota Prius, but a smaller one than the Mazda3 in a lot of urban counties in the US. The Prius and Prius Plug-In are relatively equal across the US. Having trouble keeping it straight? That's not surprising. The comparisons between plug-in and gasoline vehicles are much more nuanced than the loudest voices usually let on.

Kaz and Shiro talk Gran Turismo 7 details, Titan Nismo and more in AMA

One of the greatest innovations to come about thanks to the gigantic popularity of Reddit is the Ask Me Anything (AMA) question and answer format. The AMA becomes especially worthwhile, of course, when the person(s) answering the questions have detailed information or insight on products we love.
So, in the case of the recent AMA session with Gran Turismo creator and mastermind Kazunori Yamauchi (above), and his buddy and Nissan chief designer Shiro Nakamura (right), it was basically must-read stuff.
The pair really lived up to our expectations, too, with Kaz offering a lot of useful information about the future of the Gran Turismo franchise (especially the upcoming GT7 for Playstation 4), and Shiro promising to bring some interesting new ideas back to his colleagues at Nissan.
