Granted the sport version power trains weren't always economically inclined, but there was always a standard option.
I drive a full-sized Volvo wagon. I've also driven a full-sized Ford Taurus wagon. Plenty of room for two tall kids (my son is 6'4", my daughter is well on her way to 6'), and in the days of my Taurus, it would carry a child, a baby seat, a stroller, even a bicycle and a trailer.
Besides a thing about SUVs versus car form factors, I have test-driven Volvo's equivalent SUVs, and while they often claim similar cargo volume to the wagons, I find the wagon's long and low profile more useful for the kinds of things I tend to carry. Bikes are a lot easier in a wagon, in my experience.
YMMV.
Of course, there are F-150s and Chevy Suburbans and extra-long Escalades for those who absolutely, positively want to drive a truck.
Not to mention there are plenty of towns and cities where families get around by bike. Americans need to expect more from local governments!
New car buyer are skewing richer and richer so a larger fraction of the people OEMs have to cater to can justify the luxury of not doing that.
If they made roomier cars I’d be all for it, but they don’t. So I have to buy something that offers room.
Some people don’t want to drive vans.
