Police are generally fair I've found.
I've been caught speeding (genuine accident), gave advice, let me on my way.
Been overtaken by a Police car when doing three figure speeds and, presumably as it was 1:30, not a car in sight, they didn't care.
But then I don't (well apart from said mistake) speed when it's stupid. IMO, dead at night on the motorway, fair enough aslong as you're sensible, certain national speed limit 60 roads, fair enough.
30/40/50 roads, no. That's also where they always hide with speed guns, which IMO is fair enough.
