What would have been interesting (but for this one I'm pretty sure it's a pipe dream) is an inputable value of, say, "road width".
After all a hex is still around 50m, so there's no way of telling if that road that runs in the middle of it is 5 or 30m wide. I think I'm not the only one to have run into the problem of stacking several "paved roads" to figure highways, while a real highway is generally under 50m wide.
IMHO the ideal solution would have been to set a "lane number" value or something similar when laying down a road, which in turn changes the number of vehicles that can be stacked in one road hex, the max load the road can take, and how fast damage hampers circulation.
Not sure there's any interest in it, but pretty sure it isn't doable.
