It's not that they don't care; they're too dumb to understand the engineering part of building an ICE, diesel, or EV vehicle. All they do is follow their party's script, have staff research the negatives in a biased fashion, without cause or concern for how their actions will affect the general populace. Then, they'll have their hands out to stuff their left pockets from the lobbyists and supporters who promoted their decisions and votes.as the design is driven by the mandates of people who care less about reality and users. And that's why so many motors are failing...often early.
I believe the next few years you'll see many improved engines and vehicles being produced. The current climate in D.C. has removed obstacles and insane regulations, freeing the auto manufacturers.
