Bloomberg CityLab contributor David Zipper has been exploring the reasons why the US traffic fatality rate is so much higher than in other developed nations. In his latest detailed analysis of the problem, he concludes, “The closer you look, the clearer it becomes that the US traffic safety crisis is not a reflection of geography or culture. It is the result of policy decisions that elevated fast car travel and automaker profits over roadway safety. Other countries made different choices, and they’ve saved lives as a result.” He suggests that America study other nations’ successful tactics for improving highway safety and concentrate on how to apply the lessons here.
