This sounds right, but the actual statistics show that—for the average American—every minute of cycling increases expected lifespan by at least one minute. Obviously this is an average and won't hold true for every American in every locale.
The average American is biking for leisure. If they had to bike on their commute it totally changes and instead of a planned low-risk leisure route you're on the highway to hell in the thick of rush hour traffic. It's completely incomparable.
> If you live in most American cities, biking is basically a life hazard on par with smoking imo
That said, I used a bicycle as my primary mode of transportation in the Atlanta, Decatur, and Northern suburban areas for several years. It wasn't really all that bad despite a near-total lack of cycling infrastructure (this was before the Beltline).
