Car crashes are mysteries. Even though roughly 6 million of them happen each year in the United States alone, we seldom learn much. When we do drive by a crash, we often slow down to have a look. But there’s never much to see. Two crumpled cars. Maybe one upside down. An ambulance closing its doors. I usually feel bad—for those who may have gotten hurt (or worse), of course, but also because my rubbernecking contributes to the logjam of cars behind me.
I want to know what happened because there’s an obvious payoff. I want to make sure that the same thing doesn’t happen to me. Was it some bonehead move that I would never make? Or did someone commit a minor transgression and then pay a major price? Give me an instant replay like I get when I’m watching football. A slow-motion video with expert commentators who draw diagrams and who reveal in explicit detail how it all went down.
Without the details of how crashes happen, we tend to dismiss them as the work of “idiots”—drivers who occupy the lower echelons of driving skill and common sense. But while humankind’s measured intelligence is increasing, so is the number of deadly car crashes. After a lifetime of improvement, we saw an 8 percent jump in crash fatalities during 2015, the largest in 50 years. That number rose again in 2016, when more than 40,000 people died in collisions.
