These are gravel roads and there are over 70,000mi of them in my state alone.
This is dumb to argue over.
Gravel roads are a thing. Dirt roads are a thing. Academically, they are different.
A gravel road is an improved road(meaning it is engineered).
For cycling, 'gravel' is widely accepted to mean most any road/path that isnt paved.
This is just another example of our need to categorize and segment.
