Today it would appear the SPECs system between J22 & J23 of the M60 were switched on - with a 40mph limit. Allegedly there are roadworks taking place here. However, there are still four lanes open, (albeit one is now the hard shoulder), and the only sign of roadworks is the odd row of cones (that have been there for at least three weeks). Travelling along here after 7pm tonight I was faced with a wide open, fairly clear road but restricted to an obscenely low speed of 40 .

This is without a doubt the worst speed enforcement setup I personally have encountered - 4 open lanes with a 40mph limit, (no doubt there is worse somewhere else though). And I'm gonna have to drive through this twice daily to and from work now
By contrast the recent roadworks on the M65 were subject to a 50mph limit whilst the motorway was restricted to just two lanes. The only enforcement I saw was the occasional scam-van on a bridge.
