While I'm sure the US probably does have some bad rates. (pedestrian deaths, etc. makes sense we're bad at) I'm unsure this really corrects for the other factors. How does this correct for average mileage spent in cars per per country? Seems like mostly a function of population density and wealth? ie maybe the US has low pop density and high wealth, so unlike the highlighted Japan/France (who have great public transit / rail), we can't justify it as much but people can still afford to use cars constantly. Judging based on traffic aggression, it would seem America is actually on the more chill side compared to what I've driven in across the world. I think their recommendations to change urban spaces to make them safer make sense though, so no argument there. More just wondering if maybe our car culture is kind of baked-in to our material conditions.
