I think we both agree they could make what you describe.
We just disagree on who's fault it is that every time industry makes one approaching that, they sit unsold while ridiculous gas guzzlers are flying out the door.
They never made anything approaching that, not even close. Kind of unfair to critiscize something for never having sold when it was never available in the first place. Anything that gets good efficiency is designed to be an all-around penalty box, with no value added in exchange for the sacrifices made.
This is deliberate. The industry doesn't want to cannibalize sales of wasteful, higher margin vehicles. In the 1970s fuel crisis, when people were demanding better efficiency, we went from 12 mpg V8 musclecars to 14 mpg power-starved Ford Pintos and AMC Pacers. Downsizing the engine greatly and shrinking the car's dimensions didn't help much to improve efficiency when the weight, drag coefficient, and frontal area still matched the old guzzling musclecars. And the new "economy" cars of the period were also made deliberately ugly to discourage people from buying them. The industry then blamed fuel economy regulations!
The industry could have given us 35+ mpg V8 musclecars back then if it wanted to. You think people wouldn't have bought that? The U.S. industry decided against even trying such, and lobbied for more import restrictions and tariffs in effort to keep the Japanese out(which still failed). Those U.S. automakers that went tits-up were then bailed out with taxpayer money.
Two books that are worth reading, old, but every bit as true today as they were when published:

Tesla is the success story it is because it dared to be different and disrupt this model. Without Tesla getting EVs into the public consciousness, it is highly doubtful we'd have them available from any manufacturer even to this day. The Big 3 knew how to build something comparable to what Tesla did, 20 years prior to the existence of Tesla's first sedan, with technology not nearly as good as what Tesla had. Even the auto industries' internal marketing studies indicated people would have bought EVs in the 1990s.
We didn't get them until the 2010s, and only thanks to Tesla for daring to be a disrupter.
