And the ranking there is kind of misleading because the types of countries that collect fatalities per unit distance at all are the ones that tend to do really well on it. We don't have the data for Russia or China but guesstimating based on accidents per 100k vehicles, it's bad.

Whereas e.g. Germany does really well. But fatalities per unit distance for the US isn't even twice the number in Germany, whereas in terms of fatalities per 100k population, the US is 335% of Germany. Consistent with the bulk of the difference being explained in terms of more miles traveled.
