No one...has forced american consumers to buy ridiculously oversized SUVs and pickups for the last 2 decades.
Unfortunately, I think at least a *part* of it has indeed been the unintended consequences of Obama-era legislation.
From the 70's through the 90's, we had station wagons. They were the family car, along with the minivan. They got 20-30 MPG, and could fit between five and eight passengers, depending on model. In the 2000s, minivans and SUVs became a bit more popular, but the station wagon still existed.
Then, the MPG mandates came. Cars had to get a certain amount of MPG, irrespective of other factors (e.g. not MPG/passenger). A car that fit seven passengers simply couldn't physically make that possible. So, the station wagon died...and instead of getting 30MPG in a car, people got 15-20MPG in an SUV, because they were classed as 'trucks', which weren't required to meet those criteria.
So, anyone who would have *wanted* a smaller, car-like way of transporting larger amounts of people or things, were stuck getting an SUV or a minivan. The squeeze continued, because the sedans that *did* exist had ever-more-stringent MPG requirements placed on them, which tended to involve design changes that reduced cargo space in many cases.
Also, with more and more higher vehicles, driving a regular car means getting blinded at night with floodlights from cars at mirror-level right behind (I *always* have to turn my side mirrors down to the point of uselessness in order to avoid getting blinded by SUVs behind me), and the feeling (irrespective of accuracy) that an accident between a sedan and an SUV involves the SUV walking away with a fender replacement, and the sedan driver ending up in the morgue.
I remember a few years ago, going to California for the first time and taking note of what was driving with me on Interstate 5. California - tree-hugging, forest-fire-having, $7/gallon-gasoline California...3/4 of the vehicles within visible distance were SUVs. Really? *ALL* of them wanted an SUV purely as status symbols, and wouldn't have preferred a station wagon, or something like it, if they were both available and common enough that they felt safe in them? Don't get me wrong, I love getting 51MPG in my Elantra...but you can't tell me that the laws intended to push automakers to make that possible didn't end up putting at least *some* pressure on consumers.
