Typical argument for someone who's never lived in a place with speed cameras. The cameras themselves, sure, they're fine.
They start getting people going 10-over, but people adjust their habits accordingly, revenue drops, now they target people going 2 over.
Next they target people in school zones. All well and good. But we need to increase revenue. Parks are now school zones. Trails near the roads are now school zones. And now we're expanding the zone times from 6am-9pm. Love my 36 in a 30 along a 60 road at 2047pm ticket. GREAT.
Finally, after people get used to all the above they start messing with the limits themselves. 6 lane roads, down to 40... but not the entire thing. lets have a road that went through town from 110-90-60-90-110 turn into 110-50-90-60-70-30-40-70-50-90-60-90-110-50-110. in 8km, speed cameras at every reduction! [Calgary 16th ave] Miss a zone and you're screwed.
But that's not enough. We need to grow revenue. Lets have forward facing cameras implimented too, and take points. That way our friends in insurance can benefit too. They will even pay a bounty for each person caught.
The same goes for red lights - see the winnipeg 0.5second yellow light camera scandal.
Pilot here. We all know about airspray and their industry corner... Pay is shit. Hours are shit. Contract is shit. Offer 300k, week on-week off rotations and we can talk.
