        // driveability setting, not a cosmetic one.
        //
        //   0.0 = hugs the land: the roadbed follows the terrain exactly.
        //         Never steps, but inherits every lump the ground has.
        //   1.0 = holds a grade (default): each stretch of road is a straight
        //         ramp between its two path points, cutting through small
        //         bumps and filling small dips. Smoothest to drive.
        //
        // Values in between mix the two. Raise toward 1.0 for a more
        // engineered road, lower toward 0.0 for a more rustic one.
        //
        // NOTE: this affects road ELEVATION (terrain shape under the road),
        // not colour. Tune it properly once vehicles exist to drive on it.
