There are a number of issues with that stat. It contains a huge ton of boring not that dangerous highway miles. Highways are a separated environment that solves most of the issue with US infrastructure planning. Second, this also doesn't take into account speed reduction because of concession. So basically, the infrastructure is terrible designed but because there is just to many cars, that often masks the potential issues. Third, this also doesn't take into account the effect, that this was partly achieved by simply removing pedestrians. The US has way less walking. If you talk a more narrow look situation where there is mixed use of space, the US comes of much worse. Also this ends before the pandemic, the pandemic partly showed what US infrastructure leads to when your remove some of the congestion. This stat also doesn't show things like property damage, its funny how much car driving into buildings is a thing in US media.
