I've recently begun work on a map.
The terrain is fairly sparse, with some significant relief, and low population. The villages that are present are connected by a few predominantly level roads running along the contours.
This causes a problem as the road has a cross-slope of approximately 45 degrees, making traction interesting. When the road runs through a number of houses located at flatish bits of this terrain, but still steeper on average than say 10 degrees, the road degenerates into a chaotic mess, as each house claims a large flat plot for itself, regardless of proximity to the road or to each other, and indeed with little relationship with the building size.. the SB1 carry overs seem to have larger than average plot sizes (or are smaller buildings?)
I was somewhat dismayed by the inability to use roads correctly in this type of terrain, as the road should give a nice smooth, flat and stable surface for fast driving (so long as you don't miss the corners or drive too
), and therefore excellent (if overly predictable) BP with no appreciable trunnion cant.
As a temporary expedient, I have added a chain of bridge elements along the line of the original road, and with some provisos the effect is similar to what the roads should be. The bridge deck merely joins the two elevation points at each end in a straight line, and doesn't visually modify the underlying terrain (so partial intrusions of the underlying hill side occur to approximately the centre line of the road section). It does however give a nice flat driving surface, good BPs. It isn't possible to get good junctions with adjoining sections or particularly side-roads, and SB doesn't chain them together. Care needs to be taken not to collide with the walls near corners, as collisions with the ends/outsides of the wall are effective, even though it is possible to drive through them when leaving the road...
Despite looking a bit rough round the edges, and obviously being an abuse of the designed function of these objects, I think it is a significant improvement of the driving experience on this type of road.
