I agree 100% about the battery issue. Batteries certainly last much longer than they used to, but I very much remember my professors stating, when I started in engineering school, that the way forward is not a better battery but rather an energy source that is superior to battery power and fossil fuel. I know that the batteries on the ISS are not seeing near the degradation that was originally anticipated, but I do not know how that technology compares with what is being used by the likes of Tesla and other manufacturers. I do believe that we need something better and with more longevity than gasoline or diesel, but I am not sure if we are quite there yet. In the mean time, at least we get to have a 702hp monster truck!
