I don't understand the visibility and warning argument. There are speed limit signs prior to the cameras. That's the warning and visibility. You go over, you pay. You have been warned and informed. Drive with 40 in a 50 zone, or 70 in an 80 zone, etc. It's what most of my family does. That's the point - slowing people down.

Of course I'm aware that speed limits aren't the best way to regulate traffic speed, I'm just working in the current context where that's the infrastructure we have.
