Yes, that is literally the main reason why virtually every single inch of motorway is caked in cones and road "works" forever, as far as I know. They are all slowly being taken over by "smart" motorways that are designed with cash in mind. Those new cameras a bloody bright when they go off, so there's no mistaking when you get snapped. I was riding down the M4 near Bristol and just so happened to glance to the opposite carriageway just as someone triggered one of them. Then that Manfred Mann tune started playing... What was it called? There's one each way between almondsbury and cribbs junctions. If you are coming up the almondsbury slip going south onto the M4, the northbound one is dead opposite and leaves you blind if you are lucky enough for someone to trigger it.
