Dude… Dude. Come on. This is like a cliche about American’s warped self-perceptions. You denied the premise without explanation (“I think the death part has nothing to do with how transportation is organized outside the US,” a truly absurd thing to say) and then went … away. Far, far away.
It isn’t about whether or not Americans are “more addicted” to automobiles. Simple political choices could be made regarding road infrastructure that would save lives without requiring that people drive any less! You don’t even mention that in your multi-story wall of text that frankly no human being is ever going to do more than scan briefly. Americans are choosing to have dangerous infrastructure, when safe infrastructure exists. Driving deaths are going UP in the USA, dramatically up, while every other major jurisdiction is continuing to bring them down, some from levels a fraction of what the USA had before the recent spike. You need to have a more sophisticated model to explain it than, “Driving is American.”
