Over 1 million plug-in vehicles have been sold worldwide

We’re all for nice round numbers. So it’s great that Hybrid Cars has confirmed that there have officially been more than 1 million plug-in vehicles sold worldwide. Put another way, if you were to park those 1 million vehicles end to end (well, at least if you’re willing to assume they were all the size of Nissan Leaf vehicles), they’d stretch from Los Angeles to New York City.
