    "description": "Hitchhiking occupies a durable slot in the cultural horror catalogue: the lone figure on the roadside is almost always, in thriller fiction and true-crime podcasts, either predator or prey. Parents warn teenagers with the certainty of established fact, and police in several US states and Canadian provinces have issued formal advisories against the practice. The mental image is specific enough — isolated highway, unknown driver, no witnesses — to produce visceral discomfort even in people who have never hitched a ride. The intuitive sense is that serious harm is a realistic outcome: not certain, but plausible enough to make the activity unreasonable. Most people who hold this belief would put the assault probability somewhere in the range of 1 in 50 to 1 in 200 per trip — a magnitude that, if true, would make hitchhiking roughly as dangerous as working in coal mining by injury rate.\n",

Sample is self-selected (experienced hitchhikers using a logging app), 61% male, geographically concentrated in Europe, so the figure likely underestimates risk for infrequent, solo female hitchhikers in less familiar territory. \"Very bad\" collapses qualitatively different outcomes; physical assault alone is a subset, estimated at ~1–2 per 10,000 rides based on the proportion of serious crimes in the Cal HP 1974 data.\n",

  "caveats": "The per-ride rate of 0.06% comes from a self-selected sample of experienced hitchhikers who voluntarily log rides on Hitchlog — predominantly male (61%), young (mean age 25), and concentrated in Europe. This almost certainly understates risk for infrequent hitchhikers unfamiliar with safety norms, solo female hitchhikers, or those hitchhiking in unfamiliar regions or at night. The \"very bad\" category in the Hitchlog data collapses qualitatively different outcomes (intoxicated driver vs. sexual assault) without distinguishing them; the physical assault rate is a subset of this figure, estimated at roughly 1–2 per 10,000 rides. The 1974 California Highway Patrol study — still the most detailed crime-profile analysis available — found female hitchhikers were seven times more likely to be crime victims than males, with ~80% of those crimes being sex-related. Over 40% of all crimes occurred between 9 pm and 3 am. A 1989 German Bundeskriminalamt study (not available in full online) reached similar conclusions: physical attacks \"very rare,\" risk \"much lower than publicly perceived,\" no general prohibition recommended. The 200-ride lifetime assumption is illustrative; someone who hitchhikes 500 rides over a career faces roughly a 26% chance of a \"very bad\" incident under the same model.\n",
