Add the option to mark the current route or road segment as unavailable or ability to calculate completely alternate route for the next couple of miles. I found myself multiple times on a suggested route that was closed due to roadwork, incident or event by the police for some reason. I tried to avoid it but waze kept on routing me back that blocking point… I usually have to drive random a lot of miles until the route changes enough so that I can be given an alternate route. Happened in cities, highways (due to accident ahead). This would be quite useful to be able to mark the ahead road as temporarily blocked.
