Comment: Yes.. That was the question and number posed

It is part of it.

And that's fine, I do as well.

By the way.. here's a few numbers for you to think of as well.. If mine are correct that is..

a little over 4 million miles of roads in the US.
Around 5.25 million accidents. That's roughly 1.2 per mile.

Germany Autobahn.

7,900 something miles of roadway.
18,900 something crashes.

That's 2.39 per mile.

Of course there are other factors in play here too.. Not all of those miles are "no speed limit".

I haven't checked the amount of deaths per mile yet. Maybe later.
