When you submit a user report, a volunteer map editor finds it in http://www.waze.com/editor
and clicks on the report. Then we see "wrong route" and about a mile of what it recommended in purple and what you drove in green. If those overlap and there's no additional explanation, there's not a whole lot an editor can do other than mark it as "not identified".
When you submit a report for "wrong route", keep in mind that Waze will try to find you your shortest route (time-wise), and will never consider how much you like another for whatever reason (lack of traffic lights, scenic reasons, etc.), and will not be biased in thinking that a route is faster when it really just "feels faster". That said, in rural areas, there's probably just insufficient data to identify the correct route. Perhaps Waze thinks the route you're smart enough to take is one-way (in the wrong direction), or that you can't make that turn that you're about to make. Driving the right route a few times may clean that up automatically and will give Waze some data about average traffic speeds to make more educated decisions. Driving the wrong route, likewise, will provide average traffic speeds and help it understand that it's really slower (or maybe show you it's faster).
Aside from that, your user report might include the origin and destination so a map editor volunteer can see how bad your recommended route was.
You have map editor permissions for a mile around the areas you've driven. You might take a look yourself
and notice what's going on. The fix could be simple to see and ready for you in another week or so when the map server gets updated.
