You need to allow all users to edit maps with speed cameras and the like. Sure if you want to maintain a basemap that your power tripping editors want to keep, fine. But I should be allowed to overlay speed cameras and the like if there is a disagreement by how a local editor deems them necessary or not. You don't want to add it to the basemap? Fine. But I should be allowed to add it to a map that I use or share with my family and friends.

You also need a better reporting/dispute system that you can plead your case against local editors who think they own the map.
