Electric-car range anxiety exists, but it's overblown, says MIT study

Green Car Reports

Study MIT plug-in cars range anxietyRange anxiety, the persistent worry about not having enough battery range to finish a journey, remains one of the major obstacles to widespread electric-car adoption. Many electric cars still have shorter ranges than comparable internal-combustion models, and that continues to spook some consumers. But could those concerns be overblown? DON'T.
