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.
Other causes of death would likely look less like spiderwebs since it’s just a population density map by counties, but this one is specifically along roadways. The interesting difference between a population density map and this map specifically is you can see the long stretches of roads in the middle of nowhere and how dangerous they can be.
