I have yet to see someone doing work apart from patrolling up and down the conned lines in a "motorway maintenance vehicle" or talking coblers ! They are puting them speed cameras up because speeding its in the human nature and the laws are meant to be broken, thats why they issue a penalty charge notice ! All revenue and keeping an eye on how much you travel and where you go and come from ! Watch the next 20-30 years when the new world order will be implemented- plans of pay-as-you-go were since 20 years ago, it just takes time to get the peoples get used to them, just like the wind turbines ! Low emission zone in London ? Thats a load of bullcrap if you ask me ! They will start building suspended motorways soon its just the investments are not profitable enough unless they will tax the motorists as they please ! Imagine going to work for 10 long hours then spending a further 2 stuck in traffic boiling in your own juice ! If that happenz for long enough, when it comes to pay road chargess, you will do just to get home quicker ! In Europe, peoples comute 2-300 km one way on a daily bassis, imagine if they would spend their time stuck in traffic ?! A german/modern car has been designed to be eficient on motorway doing 70-80Mph in top gear not stuck in slow moving traffic in 2nd or 3rd gear as the daft Mayor of London tells you ! There has been a lot of abnormalities in english law system in the last decade, especially since there was that blind daft man at the Home Office...imagine what he signed- all that he aproved off ! And the new "one eyed snake" just make-it worse while blaming the previous regime ! You english better wake-up before is to late !
