You’ll drive yourself insane thinking like this. And that’s my concern about modern society. When seat belt laws were passed half a century ago, we never thought about our legs being shoved up into our pelvis. We understood that it was a “carpet bombing” law. If you force a quarter billion people to wear seat belts, it’ll prevent thousands of deaths and injuries. But me personally, whether I wear a seat belt or not, I am just as safe. People have lost sight of that today.
