Dangerous

I have to use the M20 from Maidstone to Ashford when we visit our caravan for weekends. I hate using the motorway when operation brock is in place as I hate the narrow outside lane with the concrete barrier so close. I think it is very dangerous as it is to narrow to pass HGV's safely. I am always frightened of breaking down whist in the 50 mph narrow lanes. It has gone on too long
