Motorway average speed cameras

Take your number plates off for a commute that is mostly in average speed camera territory, you're unlikely to see any police cars in these areas.

I want a set of rotating plates like James bond's Aston DB5

On my weekly commute I encounter lots of sets of road works with average speed cameras and I move into the first lane sit behind a lorry and comply with the speed limit of 50mph.
BUT I am always getting over taken and it seems that only half of the cars are doing 50, the rest seem to be going much faster. Am I missing something? does 50mph mean up to 60 or something?
I'm just surprised that so many cars seem to whizz through the cameras, I'm not going to put it to the test - as I'm sure someone will suggest

Has anyone been caught speeding on one of these average speed thingies ?
At the last count I went through 7 sets of these from Manchester to Swindon

Switch lanes after each one. They don't work then and you can go as fast as you like.

Despite what you may read in the press, SPECS is not lane specific, or limited to vehicles that enter and exit the zone in the same lane.

Not true. People thought that because when they were first used they hadn't been type-approved for that case, but that ceased to be true at least a couple of years ago.

Yes (ish). It was the case that in order to be admissible as evidence readings had to be from the same lane. From about 4 years ago:- http://www.thisislondon.co.uk/news/a...nging-lanes.do

I believe the situation has now changed a bit, paired cameras in a controlled zone are enough, if you can be certain of passing each camera in a zone in a different lane you are ok because pairing will fail.
