On my way to the old LVLO in Nottingham I would often stop for my lunch break at the services between Junction 25-26 where there is the glass sided walkway over the M1.
I've seen folk Texting whist travelling in the outside lane, not knocking HGV drivers, I would regularly see them reading a paper laid out on the dashboard with their feet up on the passenger side & foreign HGV's where the driver was watching a film on his laptop!
Little wonder folk get killed if they break down awaiting recovery on the hard shoulder. I'm amazed there aren't more big shunts on the motorways. My perception is that none hands free mobile phone use is in reality just not policed enough for it to be a deterrent.
