was towing a trailer down the M56 at bout 85 in the outside lane (there are only 2 lanes BTW so that bit is legal) quite late one eve and noticed a set of blue's on getting rather close ratehr quick so lifted off and pulled in to slow lane and slowed to 60 only to see if fly past. was very relieved as the trailer wasnt the best one ive hired and the brakes prob didnt work on it as it didnt look like it had been serviced for a while! :S wont be doing that again in a hurry as world fell out my arse when i saw the lights.
