Last night my brother and I were heading back from working away in Cumbria. Aprox 30 miles north of Stafford heading south we were in the middle lane travelling at about 80mph when a biker passed us in the outside lane at a fair speed of knots. Not that unusual, but he/she had no lights on. Can't say whether or not the biker left the motorway at the first available exit, but we followed him/her for a few miles before we lost sight of him/her. Madness utter madness.
