Seeing all the gigantic and very-high-priced Pavement Princess Pickups clogging dealer lots, it's plain that the auto industry in general didn't learn a damn thing. It's easy to point fingers in all directions, but it always ends up that we get the worst outcomes.
The auto industry is just responding to incentives, the EPA makes it way easier to hit emissions targets the larger the vehicle.
People are brainwashed into thinking a pickup truck is the only practical car even though it's the opposite. It's not just EPA regulations, it's what people want.
