They were sat on the bridge just before Jct 42 of the M6 on Thursday morning, aiming at S/B traffic but parked above the N/B carriageway, presumably to be out of sight for as long as possible due to the long right hand curve that makes up that stretch.
Going a little bit OT,but this seems to be trend nation wide, as far as I've seen /heard. I've seen them in Warks on A46 southbound, with little traffic( Hdden by a sweeping bend). Again on M74, favourite places in D & G are J3,(Abington turn off) or next one south.(J14).
All hidden by sweeping bends,and ( times I've seen them with little traffic) Another one in North Warks,targeting as site (IMHO) 300yarda away, under the camaflage of some well endowed trees. I knwe it was there(I'd passed it going the opposite direction),but from that distance it could be some bit of hoarding.
Again, they are highly visible once round the bend. But what deterrent effect does this have.
Possible parallels with the tactis used in the cold war?
But we are told speed cameras ( or as they call them ) are there to deterby VISIBLE presence.
