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.
