Groan re Operation Brock

I live in Leeds Village, to access the M20 to go towards Dover, I have to go back to junction 7, although I live by junction 8! There seems no rhyme or reason for not being able to go on at Junction 8 as the division between cars and lorries is beyond that point. I travelled to Hythe yesterday, and noted there where very few lorries in the lane designated for them, the travel restriction placed on me of 50miles per hour seemed to add to the large amount of traffic travelling my way almost 'bunching up' and the closed lane, seemed to have no sense whatsoever. The 'check points' as I travelled down were not manned, so no lorries were being stopped to be checked anyway.

It struck me that Operation brock was not needed, and the traffic would have flowed better with no restrictions other than lorries kept to the inside lane, should a check be needed at any time.
