In Brazil, these conditions are somewhat often permanent (or at least expected to be permanent) when they happen. Sometimes it's due to poor administration, which changes only every 4 years. Sometimes it's due to poor construction, which costs a lot to fix. Sometimes it's due to weather, which in many cases is not inconstant through the seasons. But sometimes they are indeed dynamic/seasonal, though it's rare to see a large (say, from grade5 to grade1, or from horrible to good smoothness), so in these cases most people will choose to either approximate the average or the pessimistic scenario (not so much different from the average). When a large change happens (in case of a natural disaster, for instance, floods), it's either temporary (the situation goes back to normal) or permanent (it takes a long time to get fixed), but not recurring (if it's fixed within a year, most people won't expect it to happen again next year at the same place, but surely it "could" repeat if the fix was poorly conducted). So I think the case of the Russians (in fact, of "snow") is quite unique.
