Yeah, you are not the only one.

There are 15000 speed cams not attached. That basically means they are of no use because data consumers (OsmAnd, etc) do not use them.

When you drive in a car you do not study the map, for small icons of cameras, you rely on your navigation to tell you there is one on road that you drive on.

So it is great that you read my note, and hopefully you will add many more speedcams.
