> You’re committing a logical fallacy here. Avoiding driving on those roads is only a mitigation if the accident rate is highly disproportional to their usage.

You're right in spirit. I actually addressed this in passing in the comment "an incredibly simple mitigation you're probably already doing". Rural roads carry less traffic than non-rural roads for the very obvious reason that most people don't live in rural areas. The disparity is documented: https://www.ncsl.org/research/transportation/traffic-safety-...

We can also note that freeway vehicle-miles (excluded from this rural roads statistic) are going to be an inflated share of driven miles precisely because the purpose of the freeway is to cover long distances.

But as to the specific number I provided ("more than a third"), you're on target in accusing me of a fallacy.
