Well it's not a smooth layout that's wanted - nobody wants roads like glass. It's a smoother mesh. A few people, myself included, think the original mesh was much better as it didn't have these pothole spikes that try to jerk the wheel rim from your hands.Well, if I understand correctly, it seems the poll results so far indicate that those polled are happy with the bumpy mesh.
Isn't there a smooth layout somewhere out there in the wilds?
The original layout and mesh can still be downloaded from RD but there's no reverse route unfortunately.
Maybe some kind person with the know-how will release an optional kn5 revision with the original road mesh added to the reverse layout. Until then it's not the end of the world and there are plenty of other tracks to drive.
