  "question": "What are the odds of dying in a car crash?",
  "quick_answer": "Dying is the rare tail. About 40,900 Americans are killed in car crashes a year — roughly 1 in 105 over a lifetime, the deadliest routine activity on this site — but around 2.4 million are injured, close to 60 injuries for every death (NHTSA, 2023). If you're weighing the risk of driving, injury of some kind, not death, is the far more likely harm.\n",

    "description": "Car crashes are the strange case where the perceived/actual gap runs the wrong way. Fear of flying sits near the top of public phobias; fear of dying in an ordinary car crash barely registers in national fear surveys at all. The Chapman Survey of American Fears Wave 10 does not even include \"dying in a car accident\" as a standalone item, though a narrower framing — being hit by a drunk driver — draws roughly two in five US adults into the \"afraid or very afraid\" bucket.\n",
