Past the sticker shock and into the driver's seat, summer road trippers wanting to take advantage of their fuel-saving vehicles are having a hard time going very far. Other than in California and the Northwest, plug-in stations are hard to find. One car manufacturer is doing something about it.

"It is very important to address this issue of long-distance travel," said Tesla Motors CEO Elon Musk in a Mercury News article. "When people buy a car, they're also buying a sense of freedom, the ability to go anywhere they want and not feel fettered." Musk has a road trip of his own planned for this summer, driving his kids across the country.
