It doesn't have to be like this though: Other countries pay attention to crashes, especially with fatalities. One of my uncles was a civil engineer working in Spain's government, now retired. All crashes reported to the police would be marked in maps, with an extra layer for fatalities. Then they'd be grouped by the kilometer of road, to look for the sections of road that were the most dangerous. The worst locations would be considered "black spots", and you'd see them in reports that hit the media. Part of the process of prioritizing road upgrades involved sending engineers in, evaluating what made the stretch of road so dangerous, and look for mitigations: From just road markings and using police as a traffic calming measure, to complete rebuilds.
The US has a whole lot more miles of road, and a lot more miles traveled, but I'd be extremely surprised if there weren't areas that prove to be far more dangerous than any other mile of road, and where some efforts couldn't minimize the problem. The way we look at traffic is so much different though: In Spain most roads where cars travel fast tend to be outside of cities. In the US, we have a wide variety of streets rated at 30-40mph, With width and sight lines like roads where you could do 60, but that are really suburban streets where people might actually attempt to cross the street. Who is going to want to track, and fix, the fact that there are a lot of accidents near a high school, in a place where people do 45mph, and teenagers are trying to cross the street to get to the only nearby convenience store?
We build more dangerously, and organize our government in ways where it's far less likely accountability will happen.
