Well, I definitely can't be turning into a Daily Mail reader because I have no problem with speed cameras either!
Wherever you drive, you should know the speed limit. It's clearly posted everywhere, and on roads where it's not posted it's easy to remember the rules. If you drive above the speed limit and happen to get caught by a camera, then you've been caught, fair and square.
Cameras are actually set to trigger at a level of +10%+2mph anyway, to allow for inaccurate speedometers, so if you're caught by a speed camera in a 50mph zone, you were probably going at over 57mph (regardless of what your speedo says!).
Some people argue that councils use them as a way of gathering revenue. I'm not sure I believe that - after all, if everyone drove at, or under, the limit, the cameras wouldn't gather any revenue at all, so councils can't rely on the money coming in from speed cameras. And anyway, even if they did, so what? If you don't want to pour money into the coffers of the local council, then don't break the speed limit - it's not a difficult equation.
Having said all that, I don't believe that successive governments' attitude to speed limits is necessarily right. The speed limit on motorways could probably be safely increased to 80 or 90mph - maybe with a statutory decrease in "bad weather". Then again, I also think we need more enforced 20mph zones in built-up areas (i.e. on housing estates, etc). But, we do currently have these speed limits and everyone knows what they are, so there's not excuse for getting caught.
More than anything else, we need better driver training and for people to take more care and attention on the roads. I regularly drive a route which has a 60mph limit along country lanes, dropping to 40mph, then 30mph, as it passes through a village. Most times I get stuck behind someone driving at 45-50mph along the fast bit, then barely dropping their speed to do 40-45mph through the village. This sort of thing can only be down to not paying any attention to the speed limit signs and a complete disregard for safety.
Right - that's enough serious stuff from me for now. No more rants!
