You are conveniently leaving out some European countries, such as Norway being at 3.0 per 1B km.
You are also conveniently leaving it the per-capita figures, with US being at 14.2 per 100k while countries like Norway, Sweden, and Finland being at 2.x, and Europe as a while being at 6.7.
So sure, "10x more" might be an exaggeration, but "2x more" is fairly accurate and even a claim of "7x more" is arguable.
The problem with both of these numbers is that they are highly sensitive to how (city/suburban/rural, freeway/highway/byway) people drive.
I haven't conveniently left out anything. I wrote my previous comments intentionally, and specified which statistic I was talking about. If you misread it, that's on you.
I used this statistic because yours is like saying the US is richer than Switzerland, if you don't divide by the number of people. Pretty irrelevant.
There is no point comparing a country that drives everywhere with a country that doesn't using a metric that doesn't account for this difference.
