wakefield road in huddersfield near my mums now has about ten cameras in a 2 mile stretch (that's not an exagerration), varying from 30,40 and to 50mph..this i believe it's excessive and clearly a cash making thing, i totally see the need for cameras on that road and usually support their use, anything to try slow down lunatics, but i think average speed check cameras would be more use in small village type locations where you don't want people slamming on the breaks you just want the ars*s to slow down the entire length of the village so they don't mow people over.
i do think cameras are a good idea in some places, but i do prefer the average speed check ones from a safety point of view. i don't agree all cameras are a cash making thing and nothing more, if people didn't speed they would be a very innefective cash making idea, i just thing their not the best thought out idea ever.
