Pickup trucks are huge in large part because of fuel efficiency regulations like CAFE which regulate fuel use per unit area. Ironically deregulating fuel efficiency would make small efficient pickups sellable again. Also repealing chicken tax would help allow economical imports. The domestic demand for remaining compact ranger/s-10/Tacoma is massive. But it's basically illegal economically to sell more.

I'd have definitely driven a compact in from Mexico were it not also illegal to permanently import them before 25 years old under most circumstances .
