Every time I go home to England I am surprised by the number of speed cameras on the roads. Pretty much every village has one, and every roadworks seems to have one too. Of course, it’s likely that most of them are fakes but 99.9% of drivers obey them. You can see some crazy fast driving on the motorway and then suddenly there is a camera sign and everyone is driving sanely until they are past it.
Something new this time was “average speed cameras”. The idea here is that there are two cameras and your average speed is computed between the two and you will be fined if that average is above the limit. I saw a couple of these, but really find it hard to believe that they are real. Is there a person reviewing all the images with a sliderule? I really can’t see a computer matching licence plates and speeds.
