Can't say I've ever really thought about this - if I follow a line feature, I stick to the right. It's rare for me to to ded-reckon on a track that follows a line feature, because it's easier to just follow a line-feature - but if my ded-reckoned track takes me along a line feature then I'll try to adjust it accordingly.
Now I start to think about it a bit, 2Donkey's advice sounds absolutely superb.
