One MAJOR flaw in that study: they're using 20 mpg as their figure for the gas powered cars. If they're doing a comparison of the current crop of electric cars vs their gas counterparts, then they need to go with 35+ mpg for the gas powered figure. Why? Because all the current electric cars in their comparison are either subcompact, compact or smallish midsize cars. That size car is NOT getting 20 mpg. Try double that.
