Nice one Soccer Cynic! I'll rise to this.
The Police, have littered just about every road in the UK with Camera signs, which apart from diluting the impact of the other signs that matter - such as the actual speed, warnings about adverse camber, schools, pedestrian crossing etc don't do a lot.
The police obviously have to put them up so that they comply(ied) with EU law, but instead of just putting them in accident hotspots, they put them along much greater stretches of road to cover their arses ("well you can't say that you weren't warded") and to allow themselves the chance to catch more offenders by being more random.
This all misses the point entirely. The speeds themselves are no longer reflective of the capability of the vehicles on the roads. The highway code specifies stopping distances, but most modern cars can easily stop within these distances and in some cases even half the distance. Older cars are much more dangerous even if they are well within the speed limit.
As an example, I know a particular corner where my car will manage it, in the wet at 70 mph. A 1986 Seat Ibiza would do it at 40 in the dry - Well within the speed limits, but dangerously fast for that car.
I have Y rated tyres on my car, which are now rated to 190mph, I bet most people don't even know what their tyre ratings are and in some cases will have a lower rating for the load carried and I can guarantee that there are a heck of a lot of people driving within the speed limits, but with tyre treads well below the legal limit.
I've had a number of speeding tickets over the years and I take them on the chin, pay the fine and take the points, I am sure I will continue to get more over the years, just an occupational hazard
I don't believe its a case of some never learning. Its a case of some actually taking a pragmatic view and realising that the laws need to be changed. Of course they won't, its too convenient for the law to remain the same.
