When Georgia voters head to the polls on July 31, some of the state's political and business leaders claim they will be deciding no less than the future of the region for decades to come. Among the most contested races on the primary ballot is a transportation infrastructure referendum that would create a penny sales tax in 12 districts across the state, potentially raising billions of dollars to fund hundreds of projects over the next 10 years. But transportation has proven a controversial candidate, and the issue could be a hard sell in the weeks leading up to the election. (AP Photo/David Goldman)

If someone were to tell you that electric vehicles are popular in Los Angeles, there's no reason to be surprised. Same thing with San Francisco and New York City. But if someone were to tell you she had collected a list of the top five EV cities in the US, which would round out the list? The picture above is a hint, if you recognize the skyline.

We'll string out the answer just a little bit by first telling you that the data comes from R.L. Polk, according to EV World, and it was Anthony Pratt, R.L. Polk's director of forecasting-Americas, that shared the data earlier this month up at the annual Management Briefing Seminars, in Traverse City, MI. If you add up the plug-in vehicles sold or leased in the five cities, you find that they make up 52 percent of all the EVs in the US. The reasons, Pratt said, are good charging infrastructure and local EV incentives like HOV lane access and tax credits.

Okay, fine, we've made you wait too long. Here's the list: San Francisco, Los Angeles, Seattle, New York, and Atlanta.
