Always have and always will. My Mother and father both had a heavy foot and of course I inherited that as well.
When photo radar came to Ontario many years ago (no longer the case, thankfully) the Gov't at that time said it was a deterrent to help people slow down only, it wasn't a money grab.
When radio stations started announcing where these cameras were located, the Gov't said that wasn't allowed.
In the radio/medias retort, being as the Gov't said it was to help only, they said they were doing the same thing so the Gov't backed off.
There is/was spots around me that were used primarily as speed trap zones and once the police/city counsel were confronted about these areas by angry citizens, they also backed off and no longer set up these traps.
90% of the laws are written for 10% of the population. If someone is driving like an idiot, then of course I don't flash them, but I think someone going 10 over, depending on the zone/area, or higher in someplace where it is perfectly acceptable to do so, then darn right I'l flash them and let them know everytime.
