I've seen that in Hungary there's the option to report at least a Closed Lane. This is also relevant for Germany. For example a closed lane on a relatively well known route of a driver could be dangerous. He's expecting a certain amount of lanes but doesn't know the newest conditions on road.
So please enable this option for drivers in Germany.

The "Oil Trace" report could be helpful as well. Often such reports are mentioned in the radio. It would be a step forward to more safety in Germany and the rest of the world to add this kind of report.
So maybe that's an option to think about.
