This thing is a major serial killer of around 40,000 Americans every year, including children, and gets away with it! Essentially, it sets the design standards that determine what road and street designs can get federal funding, and it ends up flowing down to a lot of state and local design standards. Making the relative modest changes recommended here by the National Association of City Transportation Officials would help, but really I feel like this is thinking pretty small. Maybe if we held the known serial killer, the Federal Highway Administration, to account it might deter the many copycat killers known as state and local transportation agencies.

This also reminded me of this Freakonomics podcast: The Perfect Crime. If you want to kill somebody and get away with it, just run over a pedestrian with your car.
