Earlier quoted context omitted.
It's a US thing, pedestrian safety continued to improve in France (mainly caused by infrastructure improvements), but we are starting to have the same sized cars, with the same issues)
I've always understood the US's giant car problem was an unintended consequence of the CAFE fuel efficiency legislation, why is Europe getting caught up in the giant car fad? I'd imagine that'd be much more obvious of a terrible idea when the streets are half the size.
Many Europeans are bathed in US media. They see the huge cars constantly on US footage, and some are inclined to purchase these even if they are impractical in EU towns and cities. As these behemoths are introduced in the traffic mix, others in classic smaller cars feel threathened, and their next purchase will be a big tanky SUV to feel less vulnerable.
It self-reinforces from there.
