Yeah. When rains come, bad things happen, but side drainage helps. Paving is useful, but it is stupid expensive and has to be redone, too, just not as often as dirt roadways. But, if you’re in an area unlike ours, where rain is a feature and a bug, ruts and washboarding are a thing. Even on flat forest highways in say, Apalachicola national forest, where no hills or grades are present, washboarding happens.
