Fatalities resulting from motor vehicle crashes are the third largest cause of accidental deaths in the United States. On average for 2024 there were over 100 deaths per day on US roads.
I remember reading an article a while back on how the vast majority of pedestrian deaths - even before accounting for population density - are on rural arterials during the evening and night. Something like 75% or thereabouts.
And to be clear, “rural arterial” doesn’t necessarily mean it’s outside of city limits, it’s a category of road that has no sidewalks, often no streetlights, high throughput, but still has auto-oriented businesses or homes fronting it. A road that was never meant for pedestrians but sometimes people need to walk alongside regardless.
