Some excellent points there, Ron
(you should visit the UK ..we have loads of them!!!)

In the UK, though, any Traffic Safety Devices (a posh term that the government uses for 'revenue raisers') have to have at least 100mtrs prior notification of their position - ie, they have to warn drivers that a speed-tracking device is ahead.
The law also stipulates that these cameras have to be 'in plain sight' (ie, not hidden behind a bush), and have to have reflective yellow cases.

Obviously, this is UK law and I don't know how things stand in the US...but might be worth looking into

The RAC (a motorist body) recently investigated the effectivness of these so-called traffic safety devices, and concluded that their implimentation bore no evidence of a reduction in road traffic accidents...but had helped to generate millions of £s in revenue.

And does this revenue go towards improving road surfaces, school crossing safety, or better road markings?

Does it fuck!
It goes into the pockets of the government - as does all taxes

"Example... Essex County: for 2003 they had a massive increase in Speed Cameras: issuing 94,537 Fines: which netted them £5,672,220. And the Result? in 2002 there were 92 Fatalities: in 2003 there were 116 Fatalities: a rise of 25%. An unbiased conclusion might be that the Cameras were making no noticeable difference: and it was all a waste of Time and Money. The Authority's Conclusion? the County obviously needs more Speed Cameras! Strange how any decrease is due to Speed Cameras: but any increase is nothing to do with Speed Cameras!" - http://www.roadsupervisors.net/aej.speed.htm

Sorry...I'm a professional driver, and it's a pet hate!

The bottom line is this:
You SHOULD be aware of what is going on in front of you - whether that be the colour of the lights, or if the road surface is wet, etc etc etc
Speed doesn't kill - ineffectual drivers do!

However, if less time was spent looking out for these fucking cameras, then more attention could be spent on actually driving in a safe manner.
Every sensible person... is in favour of safer roads: but we are now in the 21st Century so it is about time the Authorities packed in their patronising lectures and put some effort into developing a Plan which is a little most sophisticated than some of the garbage they are peddling at the moment. You cannot develop a higher standard of driving for a whole country by simply Punishing people in ever greater numbers: their strategies are ill-conceived: simplistic: and unworthy of public support.

All power to you, slipnslide, i hope it goes well for you - remember, ignorance isnt a defense ...that's what the lawyers will tell you, not me being an asshole
