Yeah, that's also a big factor. I think a factor would also be that EU has stricter safety laws, it's usually much harder to get a license than in the US, has better infrastructure, etc.

Not to mention that new US cars (as far as I'm aware) still don't even have a requirement to have ADAS, doesn't really help the situation. If an idiot is on their phone here, there's at least some chance that their car will brake... but even more dangerous if it's a twatmobile of course.
