I left earlier than normal for work this morning. Normal time to leave home is about 6:10am. Gets me to the M60 at about 6:20am. This morning I left earlier at 5:40am. By 5:50am I reached the M60 and all the signs were set to 60mph.
I did notice a lack of MLH's to the point only lanes one and two were in main use. Not sure what the 60mph was about but I now know it is true that MLH's are just very lazy and are not up at such times
Perhaps as mentioned above the system is learning and preparing the traffic flow
