Motorways have a minimum speed limit, (a ridiculously slow one), I believe, but may be wrong now, it used to be 40mph, unless travelling heavy haulage etc., this why tractors were banned, and incidently why they invented the GT tractor, which could travel at 40mph). About the Speed Awareness course, one is only allowed to go on one every 2 years, and after 3, one doesn't have a choice. Though if one is still speeding after that they deserve all they get. i repeat, I may be wrong nowadays, as I gave up HGV work 15 years ago.
