If anyone's wondering I've found a link that says what it is:

Interesting to note that on quite a few days over these last couple of weeks I've noticed a police Volvo parked in a little lay-by on the M56->M6 entry slip road and other days I've seen cars been pulled by the Volvos nearby. Yeah. Purely for catching tax evaders... right...
Also earlier in the week I saw someone up there who looked like he was bent over the railings being handcuffed by a copper. He was wearing farmers clothing and there was a HUGE tractor parked next to the van. Pretty easy to guess what happened up there then...
And the big cheese coppers have the nerve to come on tv/radio pleading for the public trust and respect? HA!
(In case you're wondering how I manage to notice all this, I travel at around 55mph behind the slowest truck I can find at pretty off-peak times. Works magic for keeping the petrol bills down
