Chas thee clowns that put these things in operation deal in figures, I as one Ex HGV put this in reality, the amount of people wiped out on the hard shoulder would open your eyes, the hard should is the most dangerous place to be, going back to your post, Refuge areas try telling that to the 1000s of foreign HGVs that come from Europe & beyond, for a 44 toner to pick up speed to rejoin the Inside lane will take him / her approx a mile if not more, you can guess the result of this? another thing that has not been stated regards the Hard Shoulder, the shoulder will eventually give in to the 44ton weight also the drains etc, If I can remember my Tipper days of Motorway work & delivering tarmac to the likes of the M62, there was a difference amount of hardcore + Tarmac laid on this area, so in turn " you might have guessed it" more road works.
