Speed cameras in school zones good.
Speed cameras on wide suburban roads to raise revenue bad.
Speed cameras on expressways. Should be coated with thick black paint or just stolen and destroyed...or just set to 160 km/h
Worst of all. The average speed cameras being installed in some places in the UK that log you in an out of an area and compute your average speed. The politicians who allow these should be fed their own balls deep fried with hot sauce.
I completely agree, in school, playground and secondary suburban streets, sure....put them on major roadways, thats BS and nothing more than a cash cow.
Just going to throw this out there... but, why are school zones such a sacred cow?
First of all, when school is getting in or out and there are kids all over the place, I find that 30 km/h is too fast: I'll crawl through at around 20 km/h, max.
But for the other 90% of the day, while all the kids are at their desks, the school zone is deserted. And it's usually pretty open around a school, so sight lines are clear for a hundred yards in any direction, so why the need to crawl through at a ridiculous 30 km/h? And then as soon as you leave the wide-open school zone, you're in a residential neighbourhood with trees and shrubs and parked cars for kids to hide behind, yet the speed limit becomes 50 km/h. How does that make any sense?
And of course the photo radar van loves to park in the school zone near my house, because I'd say about 95% of drivers cruise through there at a perfectly reasonable 40-50 km/h (in the middle of the day when nobody is around). If you're really serious about protecting the children, then have a uniformed cop there handing out draconian fines to the true morons who drive unsafely (and that includes parents illegally dropping off kids in "No Stopping" zones in front of crosswalks and such.)
