You misunderstand. Home Office approval applied only to systems that
recorded speeds of vehicles which maintained their lane when SPECS
cameras first appeared in 1999. So, while a change of lane didn't affect
the SPECS reading, any attempt at prosecuting a speeding driver who had
changed lanes between the two relevant SPECS photos would almost
certainly have failed on the basis that the system was being used beyond
its approved purpose.

Ah ok. Not a technical shortcoming then.

The best way of deafeting specs cameras is just remove your front
number plate which I've done on many an occasion.

Erm ... SPECS3 can read the rear number plate

Only if they point the cameras in the right direction. They don't have
x-ray vision... yet!
