To get the road endpoints blended into terrain you have to set the node type to lead-in and lead-out for the startpoint and a node before the endpoint, respectively.
I'm not sure if I understood correctly, I'm not of English origin to get the logic well.. but if I guess you told me to make the road as if a snake would bite his tail... right?Or it was something else?
I tried on a small scale with asphalt as a test:

http://postimage.org/image/qrpbf46ij/As you can see, it seems to work... a bit.But its asphalt.And probably you suggested me some other technique.Cause... on a bigger scale for example what I tried to do.. some terrains might not be so welcoming in a straight line for me just to make the "snake to bite his tail" and the terrain would be blended.And even so it still leaves behind some kind of trace that shows the merge.Not to mention on terrain that it is not straight and goes uphill in some places.
The road seems like very powerful tool, and might as well a bit improved can be used to modify the terrain.And in that way other tools for modifying the terrain or painting it may be postponed even after the release.
Especially if we could:
- introduce our own textures in to the road;
- if the road width can be greater than 204,75m; (and of course, not getting instant thrown out of the engine if we try to manually write the number in that box)
- and last if we could blend in multiple terrains properly, even if the terrain is in "waves" and not blend in only where the terrain is flat and in a straight line, but as well when the terrain is undulated, in shapes, and we could actually bend the pieces from the end so they can be as nothing is between them at their union point.
