Driving on the M6 today coming home from Manchester. In the middle lane doing around 65mph. About 50 yds behind an HGV on the inside lane. BMW X5 police car passes me on the outside doing maybe 70-75mph No flashing lights. AS SOON as he passes me he crosses the 2 lanes (pulling first, in front of me, then the HGV) stays there for about 5 seconds then crosses the 2 lanes again into the outside lane to overtake more vehicles. All the above very aggressive and without indicating. Had I have done this to him (and assuming I was not speeding) would he have pulled me over? Is this double standards or am I being touchy? Ant.
