Are drivers responsible for 94% of accidents? That is just one way to look at the issue:

In 2015, the National Highway Traffic Safety Administration, a branch of the U.S. Department of Transportation, published a two-page memo declaring that “the critical reason, which is the last event in the crash causal chain, was assigned to the driver in 94% of the crashes.” The memo, which was based on the NHTSA’s own analysis of crashes, then offered a key caveat: “Although the critical reason is an important part of the description of events leading up to the crash, it is not intended to be interpreted as the cause of the crash.”…
Seeking to find a single cause for a crash is a fundamentally flawed approach to road safety, but it underpins much of American traffic enforcement and crash prevention. After a collision, police file a report, noting who violated traffic laws and generally ignoring factors like road and vehicle design. Insurance companies, too, are structured to hold someone accountable. Drivers aren’t the only ones who face such judgments. Following a crash, a pedestrian might be blamed for crossing a street where there is no crosswalk (even if the nearest one is a quarter mile away), and a cyclist might be cited for not wearing a helmet (although a protected bike lane would have prevented the crash entirely). News stories reinforce these narratives, with stories limited to the driver who was speeding or the pedestrian who crossed against the light…
With responsibility falling on those directly involved in a crash, it’s unsurprising that so many highway-safety efforts revolve around education campaigns, assuming that if people were just more careful, we’d all be okay. Officials at the NHTSA and state DOTs pour millions of dollars into these programs, but their benefits seem modest at best. Officials “see their role as trying to cajole people on the roads to make smarter decisions,” Seth LaJeunesse, a senior research associate at the University of North Carolina’s Highway Safety Research Center, told me. “Wear a seat belt, don’t be drunk when driving, and signal appropriately. I think it’s misguided. After all, who’s going to address structural problems, if it’s just people being stupid out there on the road?”…
With the infrastructure bill now signed into law, the federal government has a chance to rethink its approach and messaging. Dumping the dangerous 94 percent myth would be a good start; deemphasizing pointless traffic-safety PR campaigns would help too. Encouraging state and local transportation agencies—not just law enforcement—to investigate crashes, which New York City is now doing, would be even better. What we need most is a reexamination of how carmakers, traffic engineers, and community members—as well as the traveling public—together bear responsibility for saving some of the thousands of lives lost annually on American roadways. Blaming human error alone is convenient, but it places all Americans in greater danger.
Put together a society based around driving and a cultural emphasis on individualism and you have this situation. Is the individual operator responsible or a system that puts people in large vehicles traveling at fast speeds?
It is less clear from this piece how to view the system as a whole in order to improve the safety of roads. There are a lot of pieces that different actors have highlighted over the years. Fewer vehicles on the road? More room for pedestrians and bicyclists? More safety features in vehicles? Lower speeds? All of these could help but they would each threaten the current system which attempts to move as many vehicles as quickly as possible.
The approach many government and business actors seem to take at the moment toward this are attempts at incremental progress. Who would put all of these pieces together in a short amount of time, especially if individual drivers are willing to take responsibility? Americans seem fairly content with traffic fatalities and pedestrian deaths.
