I don't think it's that narrow. For starters, there's a hefty chunk of the
population that lives, works, or recreates in the frozen north or a rural
setting, or would otherwise buy a pickup truck with a cab.
Sub/urban drivers who would not often require SUV features could still
benefit from them in emergency situations, but some of the gain stems from
others who are also fleeing being ill-prepared. Were LA to face a calamity
that not all could survive, I'd rather Natasha have a relative advantage.

Doesn't some of the crashworthiness derive from raw weight? Won't a heavier
instance of the same design have more crashworthiness than a lighter
version? I'm recalling homework problems involving momentum and kinetic
energy in elastic and inelastic collisions.

I'd rather see a design that could run on anything that poured or burned.
Why are diesels rare in consumer vehicles? Why didn't the steam revival
succeed? (Years back, there was a good article on them in analog. "Steamer
Time?" by Wallace West, in the 9/1968 issue.)

Many soccer moms have daughters who are into horses. In my married days, we
had a Suburban to pull a horse trailer. Damn heavy.
And wouldn't a soccer mom need to tow mobile ICBMs in an "Ungoverned"
future? I've met a few Second Amendment Sisters who'd be up for it.

Some SUVs have this. (As did our 1970 Citroen wagon. It's amusing to see
car manufacturers touting innovative features, like a second set of
headlights that are linked to the steering wheel, that we had 30 years ago.)
