QED

I'm probably a little slow (Er, yes - Ed) but I've just realised something.
I have long thought that speed cameras in France were more about revenue gathering than a safety measure.
I once was fined 90 euros for travelling at 35 in a 30 zone. I broke the speed limit, my fault so no complaint. What I objected to was the size of the fine for a relatively minor offence. It seemed to me to be totally disproportionate to the offence.
Looking at an email from Tom Tom this morning reminded me that French authorities were against sat navs that show speed cameras and either will or have banned them. To me this doesn't make sense and is also in contrast to the English viewpoint that being aware of a speed camera should make you slow down.
Anyway, you can probably see where I'm going here, if you combine the thought that French speed cameras are largely for revenue gathering and combine that with French police opposition to you being aware of them, then one sort of confirms the other.
On the other hand I could just be a grumpy old offender.
