The American car industry largely created, popularized, and continues to heavily promote the concept of huge SUVs and impractically huge pickups with high ground clearance, high weight, tall hoods and tall beds. It's almost synonymous with our national identity, in the modern automotive era.
And that domestic market seeking overseas sales is shaped by CAFE, which in combination with manufacturing conditions has almost prohibited them from making the sort of small
pickup trucks favored by the entire world before CAFE, and which remains common in the rest of the world. Sedans, minivans, even the tradesman's current best option in light commercial vans, are barely produced domestically anymore in comparison to the Lifestyle Truck, a thing which we gradually invented sometimes between 1980 and 2010 out of enclosure of small pickups, then the Soccer Mom replacing the minivan with a more vertically inclined Isuzu, then the Army HMMWV, then the F-150 and everything else just inflating in size annually.
CAFE's min-max optimization is why every marketing executive in the sector wants you to adopt an offroading hobby. That seeps out. Cultural export.
