Roads are not prints. The roads are actually "baked" into the brick. I don't think the renderer scans the brick and then creates a picture of it in any case, it's just got a library of what it draws based on what the brick is called. It draws a road brick T intersection because it reads a save file or whatever and spots a T intersection.
Most prints are too tiny to show up in any kind of discernible way anyway.
I'd actually like to see this get fixed and then maybe used by people in gallery threads as overview shots of builds. Although I suppose it wouldn't work every well on really huge builds, you can't exactly zoom in and out with it.
