You don't know how lucky you are in UK: try putting up with our Victorian State Government, who have:
Budgeted $A450 million to be raised in speeding fines this financial year
Arbitrarily rescinded the ADR (Australian Design Rules) which mandates 10% error for speed measuring devices, and instigated a
3kph error allowance only. Which happens to be the ADR tolerance on their speed cameras
Installed fixed cameras on the newest, safest highway in the state
In the process of installing point to point photo systems, to measure a vehicle over a known distance (40 km or 400 km, on the main Melbourne - Sydney Highway) to further modify driving behaviour
Run a graphic scare campaign for many years, totally allocating driving accidents to either speed or drink: no acceptance of road conditions, driving ability, etc etc
Installed fixed speed cameras on the main arterial bridge access to Melbourne, anticipating $A1 million income
per day , even though speeding and accidents are totally unrelated on the WestGate Bridge
Lowered speed limits in built up areas to 50kph, and in some places 40kph
The list goes on, but try driving at 40 kph downhill, without creeping 2-3kph up. Yesterday a number of Police Sargeants wrote to the Herald Sun adding their concern that cameras are now purely seen as revenue raising devices. Meanwhile, no copper can be bothered to enforce "normal" road laws, eg, keep to the left unless overtaking, 'cos it's too difficult to put the time into pursuing the issue if it goes to court.
