Causing unnecessary anxiety to people obeying the law is acceptable
on your planet, is it?

What possible anxiety would be caused to someone obeying the law?

That's easy to understand if you are in "understand" mode.

It goes like this... you drive along a road at 29 or 30mph.

A Gatso camera flashes the rear of your vehicle even though you are
travelling within the 30mph speed limit.

Even bearing in mind that the photographs are allegedly scrutinised
by a suppposed human before decisions are taken, you don't know what
the local authority staff will try to "prove" with the image,
especially in an area (eg, Brighton) run by half-lunatics determined
to do as much harm to visiting drivers as they can get away with.

You have moved from getting flashed by a box to being incorrectly
charged. It would be much easier if you moved to understand mode.

Please explain what purpose there can possibly be in the Gatso
flashing a vehicle which is not being driven in excess of the speed
limit (if you can, which you can't).

Nothing was said about the person(s) involved being below the posted
limit.

Er... yes, it was.

It is the central point.

See the bit above where it says: "...you drive along a road at 29 or
30mph. A Gatso camera flashes the rear of your vehicle even though you
are travelling within the 30mph speed limit".

Trigger (radar) sensitivity and enforcement threshold are not the
same thing just as they are not the same as the posted limit. The matter
at the top was about the possibility of reducing the trigger point when
the camera is taken out of the box. You would do yourself a lot of
favours if you made a better effort with your reading and comprehension
ability.

The failure to comprehend is all yours.

Someone wrote:

"I have seen boxes fitted with flash but no camera. No harm if the

I then explained the harm which is done when a speed camera is triggered
(and flashes) by a vehicle driven at the speed limit or less.

Even when a camera is active, if the authorities desire to catch on
film, say 95% (*), of drivers exceeding 36mph, it must result in 5% of
drivers doing less than 36mph getting flashed. If the human at the far
end is having a bad day, some of them get a letter. So what? They're
still breaking the law.

You seem to have a screw loose about that, even though it is 100% not
the subject under discussion. Both I, and the poster who wrote "I have
seen boxes fitted with flash but no camera. No harm if the threshold is
lowered...", were talking about vehicles being flashed at less than the
limit. It happens.

(*) 95% is just a suggestion, it could be 99% or 90% but I have no idea
of the true figure. If the spread is too wide and falses too often the
camera will run out of film more quickly.

I think you're probably right to a limited extent, in that you have no idea.
