This isn’t really true. See: Ford Maverick.

CARB only nudges manufacturers, but the market’s own purchase preferences are doing the big push.

Perhaps the biggest nudge is that gasoline is undertaxed. Consumers will never see a reason to stop driving a 18-25mpg truck when gas being less than $5 a gallon is considered a “high” price. The gas tax hasn’t kept up with inflation.

I don’t love the ford F-150 for being a monster truck, but consider this: with the right configuration it sears 6 adults comfortably, plus having a bed for cargo. Families legitimately replace minivans and other family vehicles with it, plus it can tow and haul being the body on frame truck that it is.

The fact that this tiny engine couldn't meet emissions standards is bonkers. But that's the law as written right now.

Where I live the Ford F-250 is not used for falling a single bit of anything other than air. They are in pristine shape and look like they've never been outside the city limits nor off City roads
