Graeme gurgled happily, sounding much like
they were saying:

As the tolerances for speed cameras are not advertised, then it is
foolish to risk your license by driving past at any mph above the
posted limit.

ACPO's recommended +10%+2 notwithstanding...

ACPO also recommended upping the Motorway limit to 80mph, that was
ignored as well.

You don't understand the difference between recommending a change to
legislation (which requires political agreement) and recommending a
tolerance for enforcement (which doesn't)?

I do, I was just being sarcastic. They don't have much choice with the
tolerance, car speedometers are only legally required to be accurate
within 10%.

But only in one direction. Zero tolerance in the other direction.
