You’re right, the stats are only abour helmet use or alcohol and don’t address collision fatalities.
Which is why I’ll keep my nice Chrysler minivan “cage.”
One of the recent local bike fatalities was a guy in a pickup who turned left in front of the cyclist.
The reports indicated that the helmet made no difference.
Many times we read that the biker wasn’t wearing a helmet but many times it wouldn’t have made a difference anyway. But the stats don’t usually account for that. It just goes down as another biker died because he wasn’t wearing a helmet.
Not another biker killed because of a careless driver.
