I am not clear how marking cameras *is* helping people break the law.
They rather help them *not* break the law.
At least here in Romania, such cameras are marked as present at the
entry in the area where they are present, so the only help is to
pinpoint the location, instead of being aware of an area.

Personally I find myself slightly speeding (up to 5-7km/h more than
legal) occasionaly in villages or hamlets, since the legal speed
(50km/h) is between gears, but I am extra-careful in the surveilled
areas in order not to get fined accidentally.

I know that technically/legally I am speeding, but technically, the
tachometers could have errors and practically my speeding could be
compensated by good reaction time, while somebody else, even under
legal speed limit might not have that skill.

What I am trying to say is that the the legal speed limit is an
artificial way to keep accidents under control, but since I am careful
even when I speeding, the goal is achieved anyway, and I think *that*
is the important part.

I always thought that the Mapnik render was a render for general
usage, but slightly biased toward driving and pedestrian usage. That's
way I thought it would be appropriate for cameras to be rendered in
Mapnik and Osmarender.

usage for the maps, AIUI
