Tesla’s most important feature, however, isn’t battery range or driving dynamics. It’s the charging network. Tesla has invested heavily in making sure its owners can drive across the U.S. using its Supercharger corridors, and other manufacturers simply can’t compete. Between the 200-plus mile driving range the Model S offers and the Supercharger setup, the fear of not being able to drive outside of the city is essentially erased. Until other manufacturers can offer similar nationwide charging capability, it’s going to be hard to convince most people to buy an electric car that isn’t a Tesla.
