Saw on Chinese TV that they have all these CCTV camera at all corners of city roads that they can issue ticket for talking on the phone while driving. No need to use a Police to arrest and then issue a citation.
Picture can clearly indicate you were doing it and demerit points assigned to your record too.
Good for catching person of interest when crime was committed and the person is driving on the roads.
Big Brother 1984 is just a little late (say 30 years).
