There are precisely TWO cameras in each direction - westbound there's one at start J24 and one at end, J28. Just how these can regulate speeds beats me. The only thing different is that now they have the overhead gantry notices all lit up like Christmas, saying CAMERAS NOW ACTIVE - many more gantry signs than cameras. The stretches are NOT 40mph to 60mph, they are variable, so can be switched to whatever speed they want - presumably they mean a choice of reduced limits between 40 and 60mph. But with only two cameras in each direction, it strikes me as a pretty tame operation.
Average speed cameras? I don't believe it. They are just simple old Gatsos, not even Hadecs.

If it tastes good - it's fattening.
Two of them are obesiting!!
