It might be a design choice but I can't imagine why on Earth the devs would think that Minutemen didn't historically, or for gameplay reasons, want Minutemen to gain no benefit from roads.
But just to be clear, the title says it all, I'm playing the American Civ, have researched Gunpowder, built a Minutemen unit and its ability to move through rough terrain works fine but it gains no benefit from my roads.
