I remember when speed cameras where introduced here.
We were told that they were only going to be put in black spots.
That they would only be placed within x number of K's from a speed camera
sign.
That they would take into account the average speed travelled on that piece
of road and only snap the top 10 percent.

Its funny how the sales pitch sounds fair and honest, but it only took a few years before all that meant nothing.

Its a pity really, because they did have the potential to be very good for
road safety in the right places.
Imagine if they were highly visible and just placed
- outside schools
- at really bad intersections
- just before really dangerous pieces of road

Then people would slow down for the camera, which in turn would make the
school, intersection safer.
The cameras wouldn't make a lot of money because 99% of people would
see them. But the point would be to slow them down for the right reasons in
the right places.

You only need to watch local people driving past a fixed speed camera
to see this in action.

Unfortunately slowing drivers down for 100 meters on a motorway achieves nothing.
