Other countries: In china, you have a CCTV cam every 2~5miles. Tracks your movements, snap HD pics and all. Street/Blvd/Freeway/Highways, we got them everywhere. Seat belt, talking hand-on phone, over speeding, illegal lane switching, it-s-all-there. They even send you an email within 24hrs along with your pics attached.
Our radar detectors here are Mobile APP which track your location/gps and that app 'buzz' you the CCTV cams ahead lolll If you as a driver find a new hidden cam, you can upload its location using that same app (contribute). Pretty illegal stuff... my wife has it on her phone... cool chick
