That might be true, RWY in sight.
Yet, I myself have a feeling (I said "feeling", and I may well be proven wrong in the years to come, and should I say, I even wish to be wrong?):
I think that the underlying truth of this whole story is that we are witnessing that battery evolution is coming to its end. This because of the intrinsic limits of the involved electro-chemistry that have been underestimated.
In paralell to the problems in aviation (that will be solved by alternate existing technology at great expense and big loss of the dreamliner's performance) battery-based individual automobiles as means of mass transportation may prove to be another dead end.
We'll see.....
