I already answered that somewhere else we update speed cameras whe we get them from our supplier, it is not regular you can import your own using digger
The set of OSM speed cameras used to be very very small ... maybe it changed. I am talking about Tag:highway=speed_camera. I see there 12703 nodes now, so maybe it could be processed (?)
I see - you mean to make speedcams _part of the map_? The only counter example I can think of now is that some people may not want speed cameras at all (or they are prohibited in that particular country). We will discuss that. thanks Martin
