Now that I think about it, someone should make road textures for the Mod terrain pack. In particular that plate one.
They could have asphalt/gravel/concrete texture for one and a overlay with the road lane splitter for a second. If you would put them on 8x8s You could have a xvx, x being normal and v being lane splitter and you would have a 24x8 lane modular piece, which could become wider as well.
Or that too. Yeah that could work too. or some sort of road that doesn't collide with the terrain pack. Mostly because the ground textures But if someone manages to do another terrain pack, 1x, 2x, 4x, being width 1x, 2x, 8x, 16x and 32x we could get really nice buildings
