I'm not pessimistic about "the outlook of future EVs".
In fact, I think they are perfect in certain circumstances.
What I am pessimistic of is the central planning mentality that is choosing EVs as the ultimate solution before the jury is out, and mandating putting the cart before the ox. We are going to waste a fortune on technology that is not ready for prime time and may actually be obsolete before anywhere near being in place.
For example, what if there is another technological break-through in some other area, like fuel cells, after we've spent a trillion dollars putting charging stations everywhere?
I think that EVs should be sold on the basis of what they are good at; efficient short-range transportation for people who travel less than 100 miles a day, and stop trying to convince people that they're going to be taking cross-country trips in them.
