Tesla has lately made roadtrips a big part of the publicity campaign for its network of proprietary Supercharger fast-charging stations. Perhaps one of the most significant routes is now covered, with Tesla CEO Elon Musk sharing via Twitter than the Los Angeles to New York Route is now covered with fast chargers to allow coast-to-coast road trips in the Model S and future Tesla models equipped with the fast-charging option.

Tesla had earlier staged roadtrips to highlight the coverage of the East Coast corridor from Boston to Washington D.C., as well as from San Diego, California to Vancouver, British Columbia. For the company's European debut of its Supercharger network, it chose electric vehicle-friendly Norway before starting to build it out on the continent, with the majority of chargers currently located in Germany.

To highlight the construction of the L.A. to New York Supercharger corridor, two teams drove from coast-to-coast over the weekend, and Musk tweeted he was going to take a coast-to-coast Spring Break road trip, and jokingly added he had the family watch National Lampoon's "Vacation" as preparation.

On the company's Web site, plans are to have most of the nation covered by Supercharger stations by the end of 2015 to coincide with the expected debut of Tesla's mass-market model targeted to start around or below $40,000.
