I don't agree speed cameras should be conceled, I suppose the logic is that you'd not speed INCASE there was one.
But they are supposed to get people to slow at certain places.
What has to happen it a change of mind set like happened with seat belts, drink driving & is happening with mobile phones.
Attitudes need to change, that takes time.
When i passed my PCV test at 18 years old i was on a restriction, part of witch meant that if i got one point i'd loose my PCV & have to re-test at 21 to get it back, I've always kept to the limits because of this.
Yes its easy to miss a sign on a strange road or just creep over the limit. We have the technology to solve it with GPS speed limiters, i'd have one but how many others would surrender to technology. I've driven coaches for years at a limit of 100kph so it doesn't bother me at all.
Sorry to preach but a final word
IF YOU DON'T SPEED YOU WON'T GET DONE FOR SPEEDING!

P.s. i got done 7 years ago 49mph in a 40 zone, road i knew well but a new limit, i'm guilty, the signs were there to be seen. I was driving a coach with 30 people on. I deserved it.
