I disagree.
Speed cameras on Motorways are not the most effective use of resources to prevent accidents and death/injury. The "speed kills" message is a superficial and facile attempt at solving a very complex problem. Like most simple proposals to solve complex problems, it is wrong. Statistically most accidents and certainly most fatal accidents happen on minor single carriageway roads. Yet these type of roads, even known 'blackspots' are rarely equipped with speed detection or police patrols. Why? Perhaps the relative lack of traffic and a steady stream of fines as is available on busy moterways! Speeding is relative and depends on weather, traffic, visibility, road condition, driver competence and experience. To reduce it to a simple formula of 100 and x per cent of y is ludicrous. This is symtomatic of a bureaucratic mindset that wants to tick off the "We must do something about road safety" box. Oh, and a healthy stream of revenue too from the already overburdened motorist.
To really do something effective about road safety would have to start in the schools with a comprehensive driver education programme. Ideally, alll drivers should be encouraged/subsidised/incentivised to complete the Institute of Advanced Motorists test or some similar program. But this would cost money, wouldn't it? Are we likely to see it?? Two chances I'm afraid!
On a lighter note, try applying a light coating of vaseline to your number plate (during winter months) This will attract enough mud and grime to render the number plate illegible to the cameras. (Be prepared to leave your car unwashed for long periods)With large numbers of photographs and stretched police resources, you will fall between the cracks while the easy targets are fleeced.
More seriously, I am appalled from a civil liberties point of view at the seeming absence of safeguards that this data will only be used for the purposes specified.
The price of liberty is eternal vigilence.
