Based on us distance data from https://www.bts.gov/content/us-passenger-miles, europe distance data from and death rates from https://crashstats.nhtsa.dot.gov/Api/Public/ViewPublication/... for US, https://www.statista.com/statistics/1331134/road-traffic-fat... for germany, and https://www.statista.com/statistics/1240414/fatalities-in-tr... for norway It looks like in 2021 the death rate per km driven:

US is 42,939deaths/5,349,230 million miles = 0.0050 deaths per million km

Germany (2020) 2,719 deaths/718056 million kilometers = 0.0039 deaths per million km

Norway 80 deaths/68232 million kilometers = 0.0012 deaths per million km

It certainly looks better for the US than it does when looking at deaths per capita, or deaths per vehicle. Though US still looks bad. You could argue US driving way more per capita is might also be due to bad design that makes for more traffic deaths
