It was kind of dumb to have those cameras there. Everyone knew where they were and would just drive 45 when they came up to the camera zones. I think I may have seen them flash just once or twice in all the years they were there. Not even really sure about that.
I went through one on my way to band practice every week when I lived in Seattle. I could get it to flash me every time. But I always stopped in time. Never got a ticket.
It became a sort of cat and mouse game, kinda like I did with traffic cops when I used to fix cash machines.
