Might be road design. I think european roads are generally narrower than US roads which have 12' wide lanes. I remember the F-150 raptor was > 7' wide (without mirrors).
Yeah, it's pretty normal with automotive regulation to promote whatever domestic manufacturers make over imports. In the US, EPA regulations so heavily favored domestic trucks that that PT Cruiser was somewhat famously classified as a truck.
The trend is that roads are becoming more dangerous in the US, with the cars being bigger as a major contributor.
People in US are fine with increasing casualties for some reason, and I’m glad that in EU the general consensus is to continue with keeping roads safer.
