I don't agree with your wording here, Herr Deutschlander, but I do agree with a fundamental premise you make, based on 40 years of driving and living in both the UK and in USA:
American cars are big and heavy and built and bought with the logic, "no matter what, (even if its my old grandmother's fault,) everyone in the car will be safe.. whatever happens!" This is how we choose/buy cars for our young, for our aged, for those we want to protect from themselves. It is the American Alter of curb weight. I never did get the whole SUV craze. I prefer my [sporty coupe.]
European cars by contrast (and maybe because fuel is so much more expensive) have until recently been smaller, with an emphasis on handling, braking, and performance. In Europe, driving is not a right but a privilege, and it must be earned. The build and buy logic is to buy the car which is safest in the hands of a competent driver. Rather than focus on safety when a driver screws up, focus on the best ability to stay out of trouble in the first place.
Of course there are knobheads who drive their US rolling tank, or UK boy racer, like they don't care whether they or anyone else lives or dies. Moreover, 40 years has seen traffic rise to a level unthinkable when I got my license, making silly bugger speeds increasingly problematic. But I've never been in an accident, and it's not because I drive within the absolute limits of the lowest common denominator. And when I rent American fleet cars, I drive them like a baby, secure in the knowledge that I could drive into a tree and not notice, but fearing it will happen through no fault of my own.
