I've always wondered if it wouldn't be easier to use the grid to power cars instead of thousands of tank trucks on a daily basis to fill our gas stations which at the same time consume more gasoline.

From the practical point of view, we should use the oil to generate electricity, not to run our cars. Until we find a way to replace oil with nuclear, fision or whatever, then the grid remains intact we only change the source. And cars remain electric without any change.

See? blame BigOil for stomping his boot on the head of progress...
