Risk Factors Interpretation
The grim calculus of cycling suggests that while a helmeted, sober, alert, and well-lit rider on a calm, dry street in daylight still faces considerable risk, the odds of calamity spike dramatically when you add youth, speed, darkness, drink, distraction, or the sudden opening of a car door into the equation.
