This enables transport drones to drive on various modded surfaces. It currently supports:

• Asphalt Roads - all asphalt road surfaces are supported
• Asphalt Roads in space - if Space Exploration is installed, then asphalt roads will be placable in space to enable in-space asphalt road networks
• PyIndustries aslphalt - the asphalt tiles supplied by PyIndustries can now be used for transport drones

To use, simply install this mod and then optionally install the other supported mods. When you next load your game, the road surfaces should behave as expected.
