I love the way statistics are manipulated. Two years ago a stgretch of motorway close to Exeter was used to test and evaluate the SPECS speed camera system. This area was nominated because of the number of serious injury accidents although in reality it is an excellent carriageway, well lit and extremely safe.
This experiment lasted 12 months and was deemed a great success in so far as it reduced speeds but it also reduced SIGNIFICANTLY the numbers of people prosecuted for speeding.
They based this on the fact that they used it during a period when there were road works. Prior to the SPEC system they had the standard speed camera and a significant number of drivers were prosecuted. When the SPECS system was installed, the speed dropped and the prosecutions dropped even more
This exact same stretch of motorway is now the subject of a further test. This time they are going to switch off the lighting. The reasons they have decided this road is a suitable location is because...... It is deemed an exceptionally safe location that very rarely over the last several years has any serious road traffic accidents
Statistics
They make experts look like liars and liars look like experts.
