> If their new batteries can get 40 miles on a "tank", and be refueled as easily as my car can now, that seems right on the threshold of being a very viable product. Not really. I go 300 miles between fillups and would like to go more. 10x as many visits to the "energy station" is a huge obstacle. Not to mention that I often go on trips that are longer than 40 miles. Losing 5 minutes to fillups every 3-40 miles is unworkable. And, I often go places where the gas station density is low, so I'm going to have to fill up more often and there are places that I just can't go on a 3-40 mile tank. As a commute-only vehicle, 30-40 miles can make sense, but few of us can afford significant money for such an "extra" car.
