Even with the losses through transmitting power down lines (which you could just put up a few solar panels like the charging stations out in CA. Before the state got sued by the big car companies for instuting a zero emission law that required like 1% of their cars to be zero emission to sell their cars there) check this site out to see how much more inefficient your car is. http://www.fueleconomy.gov/feg/atv.shtml
Even with coal power your car is still vastly more inefficient. Modern cars with CVT's pistons that shut down and all this other extremely complicated equipment are needed just to make it slightly more efficient at which point you the consumer lose in the end from maintenance.
Most people are willing to point fingers and not research the possibilities. if nothing else rent "who killed the electric car" and that is a documentary based off old technology which addresses everything you just said. Also read this http://www.metricmind.com/ac_honda/main.htm
