Road Surface Pathfinding Enhancement

A lot of players are using the new surfaces to make roads for trucks, which currently trucks pretty much completely ignore in favour of faster more curvy routes, If floor surfaces also gave say a 10% boost to vehicle movement because it isnt bouncing along rough ground that would also mean the pathfinding for trucks could take into account finding the fastest path VIA the road networks where applicable which would also keep the trucks on our roads more meaning less maintenance as intended.
They'd still be free to take weird shortcuts but where a faster usable road IS available would be nice for them to actually use the road.

Properly working roads are already planned. I believe for Update 3.

Post Update 3; roads weren't added... but Satisfactory has new vehicle pathing in it's next major update, 1.2, looks very inspirational.
It might be a potential way of laying roads in CoI, make it an extra visual layer and allow it to be copied and pasted like normal. Vehicles see these paths as an increased weight (due to increased speed) with it pathfinding calculations (meaning it will use it if going in that direction). Bridges automatically add them to roads, just like rail lines.
This gives us as players the ability to customize roads as we see fit whilst also allowing ease of implementation (since Captains only need to implement basic indicators ui).
