In my view the world is broken into 2 groups, car people and consumers and there are way more of the latter. Consumers care less for 6 speed manual transmissions and more for 6 cup holders. I live opposite a school and there is 1 guy who has a cool car that he occasionally brings. The rest are the usual mix of wagons and SUXs. Most couldn't tell you which wheels were driven. To them the choice between EV and ICE is largely moot.
So what is a car company to do? You could take the Dodge route and build wacky Hemi SUVs, or switch to electric motors which are much cheaper and more reliable. Bean counters will beat engineers every time in that battle.
So Jack would you have us rage, rage against the dying of the light? The 76 Cadillac is illuminating. GM could have built the 77 convertible, it is only a question of engineering it to meet the safety standards. That would push up the price (and probably the weight) and I'll wager that the market wasn't there for it. So flog it as the last of the breed and move on.
But force them, through articles and purchasing to build some interesting EVs, not just SUXs with an electric motor where an engine once sat.
I really wish this wasn't the end for Cadillac and V8's, turbos, etc. Sadly an all electric Cadillac has zero interest for me. I have had the chance to drive the 1st and second generation CTS-V and loved both cars. They drive fantastic. I never drove the ATS, the back seat was a joke in the sedan. Interiors were "meh" but I guess that is why they depreciated nicely. I have not had a chance to drive the 3rd and likely not going to get to try the upcoming "Blackwing" models. I still don't understand why the "Blackwing" moniker is a thing without the engine to go along with it, but I guess I never will. I still don't see why they have to be electric only. Why not some transition where there is both? I'm not going to go electric right now, they are nice but they still don't equal my least fuel-efficient car in terms of go anywhere and anytime. I think I'm going to go get a Lexus IS 500 and get the last of the NA V8's.
