First of all, "electric cars" don't save fuel, and by that I mean more than just perceived fuel mileage.
You must consider the "end to end" costs, materials, and energy of building, shipping, maintaining, fueling, and destroying old cars
So far, NO body has come up with a long term fuel supply for "electric cars" that does NOT already impact the already overtaxed power grid.
I'm speaking of course about such things as solar.
Next, NO body has a solution for anybody that actually wants to DRIVE.
I look back when I worked in Spokane. I get up at zero:dark:thirty, grab my lunch, tools, other gear and clothes, and go out to the "electric car"
So the "electric car" has to make the 45 miles to Spokane to work, and DURING that time, it has to run the ELECTRIC heater/ defroster, the ELECTRIC headlights, the ELECTRIC radio/ stereo, and the ELECTRIC drive system.
So, two, three, four years later, the super-expensive-high-tech batteries (just like in my camera/ laptop/ cellphone) are NOW only capable of some reduced percentage of performance, say, 30-60 percent of when they were new.
Does this mean I want to spend 16-40 GRAND on a new "battery pack?" uh, NO!!
Is this car going to be resellable?
(Sample ad) FOR SALE, 2525 ToyKitiac, looks and runs good, NEEDS NEW BATTERY
We have GOT to figure out "alternative" energy sources, like solar, to reduce fuel consumption OF ALL TYPES. The world use of fuel is overwhelmingly coal and oil. Until we can change that, "electric cars" are not gonna be "the thing."
