" ..Plug’n Drive’s calculations show that most people spend $2,500 to $3,000 per year on gas. Those who switch to electric spend about $500 to fuel their vehicle. ."

Entirely misleading - there is currently no "road tax" and others on electricity. By the time you add the equivalent of taxes on gasoline and diesel to the cost of charging I doubt that there would be much if any difference ! Then there are the subsidies .... Currently all such costs are hidden from the consumer, and one might expect our media to illuminate such realities.

I guess our highway infrastructure will be built by the Seven Dwarfs and electric vehicles provided by the Good Fairy - as long a we provide the pumpkins  .-)
