Is there really that much induced demand in rural interstate highways? They're congested rarely enough and still almost everywhere the standard 4 lane interstate can handle things without seeing demand fill the available capacity. Certain corridors see increased demand at times but that's because of the surrounding communities happening to grow (and thus need more goods delivered / ability to ship goods) more than the highways necessarily inducing that growth.

I understand that induced demand is a thing in sprawling metropolis where transport is the bottleneck preventing growth in certain areas, but this feels like a different situation.
