Thanks for your vote of confidence. A lot of those idiots who drive at ridiculous speeds on the motorway finish up with a ban. As for smart motorways, they didn't exist in my day so I have no experience of policing them but, as a driver, I refuse to use them as I think that they are dangerous. Get a breakdown or a puncture and you've nowhere to go other than sit in a live lane and wait for someone to run into the back of you. My advice in that case would be to get out of the car and as far away as possible. The death rate on smart motorways per mile is well above that of normal motorways.

I live in Nottingham 5 minutes from J26 of the M1 and my son lives in Leeds so the M1 would be very convenient. The smart motorway starts at J28 and on the one occasion I used it the red X came on over the inside lane together with the speed limit sign indicating 50mph.. I pulled into lane 2 and slowed to 50 only to be overtaken on the inside by a number of lorries; mostly with foreign registrations. There was a car broken down in lane 1 and how there wasn't an accident as I was approaching it I'll never know. There were vehicles swerving all over the place. I now go up the A1.
Incidentally, you should never go onto a motorway if you're low on fuel.
