TOP GEAR RACING ...WERE THEY PULLED BY POLICE!?...(1)

May 19th 2014 on the M6 near Preston Lancs.
On entering the M6 at Leyland about 12 noon I was passed by a black 4WD towing a huge trailer. The trailer had Ferrari logos and the title 'TOP GEAR RACING' all over the sides and back.
I followed the trailer for several miles before I had to come off at 31a. In the meantime, the 4WD and trailer had been travelling at a MINIMUM speed of 70mph before the police showed up.
At times it touched 78mph !!... and only slowed up when a police car pulled up alongside him and another police car fell in behind.
See on the video where the police pulls along side the 4WD when he's doing 70mph uphill in the third lane and see him slow down to the regulation 60mph. Then see the same police car pull in front and another police car pulls alongside the 4WD. He then drops in behind and it is at that moment I have to leave the motorway. The traffic is heavy on the inside two lanes which is possibly why the the cops couldn't pull him over straight away.
This video is one of two showing the progress of the journey and I will try to join them together later if YouTube editor allows.
In the meantime I will describe them as 1 & 2.
What do other people think?
Should he have been speeding up to nearly 80mph or, did they even stop them........ in your opinion?.

Don't forget, this is only one video of two. Please see the second film when the police arrive on the scene. The second video has the same title plus.... (2)
