A 2016 study done by the NHTSA, which apparently has yet to be replicated, examined key factors in cycling fatalities. That year motorists killed 840 cyclists.
> 71% died in urban accidents> 29% died on rural roads > 51% died in daylight hours> 5% died between dawn or dusk > 48% died at night. Winter months are by far the most dangerous.
> The average age among fatalities was 46 with 50- to 59-year-olds accounting for 24% of all deaths. > men died at 5.6 times the rate of women> Children under age 15 tallied 7% of all fatalities. Alcohol usage among cyclists was a contributing factor in a quarter of all fatalities.
> 4% had blood alcohol levels between .01 and .07.> A staggering 21% of cyclists — 171 — had blood alcohol levels exceeding .08.Don't ride drunk at night in the city without a helmet, you hipsters
