Some of us remember when our auto industry was selling rather obsolete cars and suddenly fuel prices rose and nobody wanted "land yachts" any more. Chrysler would be long dead now if not for the foresightedness of the president in seeing the Horizon being developed in Europe and saying, "We want that" - and then, a bit belatedly, realizing they could Americanize the design and make the Reliant.
In 1981, there was almost no market for traditional American cars. That could happen again. The Middle East is a power keg again, with Qatar and Iran fighting a proxy war against the Saudis, Iraq, and Israel. (Which is why the leadership of Hamas lives in luxury in Qatar, not in Gaza, and why the Houthis are aiming rockets at European cargo ships and Israel alike.) The US has zero extra refinery capacity. If we start using more, not less, gasoline and one of those refineries goes out from an accident (with OSHA all but dead) or from terrorism (most anti-terrorist specialists have already been fired), what'll happen to companies that bet 100% on big gasoline vehicles?
Sure, sounds paranoid if you don't know the history behind the 1970s oil crises and if you don't keep up with tech news. As it happens, between arstechnica.com and military.com, you can see exactly how we're making disaster much more likely.
... of course if we erect really tight trade barriers, the auto industry would survive since there'd be no foreign cars coming in...
