I think you'll find the cameras only operate when the variable speed
limit is in operation, since that's their declared purpose

I know that you will find that your statement is incorrect. The
cameras also function when VSL is not in operation. Finding out what
limit the cameras are set for is difficult, but I have seen cameras
flashing drivers exceeding 100mph in areas where VSL gantries exist
but were not in operation.

You have mentioned that before. That why I slow down to a 95mph when passing
them.
