This week, millions of Americans will climb into their cars to visit family. Unfortunately, they will have to travel on the most dangerous roads in the industrialized world.

It didn’t used to be this way. A generation ago, driving in the United States was relatively safe. Fatality rates here in 1990 were roughly 10 percent lower than in Canada and Australia, two other affluent nations with a lot of open road.

Over the last few decades, however, other countries have embarked on evidence-based campaigns to reduce vehicle crashes. The United States has not. The fatality rate has still fallen here, thanks partly to safer vehicles, but it’s fallen far less than anywhere else.
