Its only really sharp bends and in a way it isn't even the roads themselves. What it is is that the roads show you how the underlying terrain makes the ai decide to move because the path of the road will (mostly) be the path of least movement cost. The ai will still glitch moving over the same terrain without a road. But if you can get the roads between settlements gradually curving with no sharp bends and no cutting back on itself then the ai will glitch much less.

I think the game ai will never be as good as it could be unless map makers find and fix these glitchs. Someone with a lot of patience could make a glitch free and accurate map probably. Just take a lot of tiny terrain changes, testing and patience. (I think)
