Regardless of any safety claims, for that reason alone, I don't see it as a politically viable issue.
I don't think it's politically impossible. These things are killing children (among many other people). "Giant trucks and SUVs are killing children" seems like a pretty powerful line.
Assault rifles have been used to slaughter classrooms full of children in some of the most bone-chilling acts of violence imaginable, and people have such a weird identity complex around guns that they go to outrageous lengths to avoid any meaningful action. We've even seen parents of murdered children accused by gun-rights activists of being paid actors and deliberately threatening 2nd amendment rights.
Car culture in America is similarly toxic, with people having strong automobile-centric identities. The culture surrounding giant trucks is the most extreme, and there's a mountain of dashcam video online suggesting that the kinds of people who buy these massive truck are also quite reckless behind the wheel and do intentionally aggressive things with them, including deliberately harassing behaviors like "rolling coal". These aesthetics and behaviors are enshrined by popular political establishments on the right, meaning that challenging any of it becomes a partisan fight.
The backlash of banning these kinds of vehicles would be straight out of the movie Idiocracy, but there are enough jerks in this country that it would completely block any progress from ever being made.
I think people simply do find SUVs (which I don't like) convenient. Many women, including a huge number of moms, do happen to just love SUVs. Both in the US and in the EU.
In the EU SUVs are now approaching 60% of all cars sold (59.25% or so, latest numbers). You don't get such a market share by being mostly cars sold to men needing to "gender-affirm".
A Ford F150 is fucking ridiculous in comparison, and larger than any truck I remember seeing growing up, and there's people with F350s for personal use.
One of them ran over and killed a kid outside a nearby children's museum. Those things are not safe.
They more or less have the capabilities of a small pickup truck, but exchange the bed for more passenger space and inside cargo room. A minivan does have more space, but cannot tow and would immediately get stuck in the first mud patch it sees.
I have no idea why people in the city buy them though (other than snowy regions).
Watch a US truck commercial. The market and the motivating themes are immediately obvious. Besides, drivers literally adorn trucks with prosthetic testicles. That's something that cannot be unseen.
I don't think I've ever heard any man ever say that in real life, but even online it's probably been almost a decade since this was memed into the ground.
Um, because men get weird when you point out the gender-affirming actions they do? Try it irl and see what the reactions are. There's a reason the only place free of physical intimidation is where this can be safely said.
Besides, how old is the privacy comment or the "parents should parent" comment we see dragged out on every kid's social media ban? It's almost like the age of the sentiment doesn't have any bearing on its relevancy.
