Infamous,
It might also be argued that the power stations, whose specialty it is to generate power, may be so efficient in their method that the losses from transmission would cancel out. Since the vehicles primary speciality is transportation, it may be a less efficient converter of fossil fuel to power than the energy station, and it could still be more efficient to transport from the station to the electric car...
Just a thought. I haven't done any research on this to support the idea.
Cheers.
