(94% involved poor driving or bicycle riding practices) (42% a bike factor only, 36% both a bike and vehicle factor, only 20% by vehicle alone,) meaning that if you follow signals and pay attention you are about 5x less likely to die when riding a bike)
And I would guess 90% plus don't wear helmets anyways. (only 14-20% of bicycling student reported wearing a helmet in the past year) about the same rate reported by other cyclists.
Let's say half those always wore a helmet, (so about a 3x decrease in risk to die) (makes since as helmets can't prevent all fatal injuries, and 74% of fatal injuries were head injuries)
Disproportional deaths from large vehicles (32% of deaths, 17% of toll collected on bridges 5% of vehicles registered). Stay away from or behind truck and buses,
