I do think that there has been louder voices coming to the fore but the Speed Industry has been quietly getting well ingrained into the system to ensure it's survival for some time to come, very sadly.
People do on the whole seem to completely disagree with scams though. They know they are wrong because they know that the speed setting changes according to conditions. A few mph above or below the limit when it is totally safe is not going to result per se in carnage on the roads. Their preaching that scams and slower is safer is instinctively known to be utter rubbish to those who have a good and experienced understanding of driving / riding.
Many people who I talk to in the press are often grateful that I can explain what they have been struggling to for some time...
The fight continues....
I think that people seem far more aware that the scams are money-generating and so see it as such.
If the Law removed the criminal element from a 'speed ticket' and it was 'just' a fine then I think there would be less objection to them on the whole as people wouldn't see them as the threat to their livelihood as they are today.
Neigh everyone when they do get a NIP still comment "But I wasn't dangerous". The former 'speeding' ticket being directly associated with dangerous situations, still sits in people's minds.
