So, that's the full story :-)

Its worth keeping in mind that they are not usually set to trigger any
lower than at the ACPO guideline speed (10% + 2mph), so 77mph on a
motorway, and vehicle speedos are not permitted to under read - hence
most err on the side of caution. Hence a speedo indicated 70 mph may
often mean an actual speed somewhat less than that.

Combine those two, and in many vehicles you would need to be doing an
indicated 85+ to have a problem.

Every couple of weeks, we get a 'suitcase' speed measuring and
displaying gizmo bolted onto a lamp post coming into our village. As
that is reading 30 mph, the speedo in my Focus is indicating 34 mph

The ones that pee me off flash up 30 when you drive toward them at a
GPS indicated 26 or 27... you can tell that someone has "calibrated"
it to trigger on a speedo "30"


the irritating one here locally is the one that flashes '40' at you but
is set to '30' and the one that is set to detect if you are speeding OUT
of the village as well as IN..
