I HATE these things, but i can understand them on intersection. The ones the bug me big time are on long straights with clear visibilty, good surfaces where it probably be safe to exceed the speed limit by quite a lot. Would it be cynical to say that these ones are placed more for the revenue than saftey?

But the flash from one is quite distinctive, if you were driving into the sun you might miss it, but most times youd catch it in the mirrors.
