That's actually the real point. Transmitting electricity is horribly inefficient, compared to transporting portable fuel. The energy required to send a car 500 kilometers is approximately 50 litres of gasolene. Transporting 50 litres of gasolene to a fuel station by truck costs no more than the truck expense, and the truck's fuel expense, and the road wear and tear. And the larger the truck, the less it costs per litre.
But for the electricity, not only is there transmission loss, but there's also repeaters, lines, equipment along the way, the maintenance of that equipment, accessing that equipment, oh it's horrible. Maintaining infrastructure is a horrible horrible game when you're outside of a major city's orbit.
Think of a mountain range, with 10'000 miles of road. No cities at all. You can build wires, and repeaters, and blast mountains, and fix ice storms, or you can just drive the fuel to the stations.
Electricity is only useful within city limits -- like just about all infrastructure systems.
City limits (3.5% of the land area) hosts over 60% of the American population (the majority of which have commute times less than 2 hours.) The majority who drive cannot afford to travel the way you do that frequently anyways, so energy policy should be catering to them, not you.
