Is the EV transformation of the market over hyped ?

It's totally immaterial to argue over it. Nobody will convince anyone else, and EV's work well in some markets and not so well in other markets, and are non-existent in still other markets. They aren't going to be a majority any time soon. Maybe 10 years they'll have a significant foothold on either coast, with slow encroachment in the midwest, and midsouth.
