No way would I sit in a car for 34 minutes in lane1.
I wouldn't sit in the car for 3 minutes on the hard shoulder, let alone a running lane - it only takes one dozing driver wandering onto the hard shoulder and you're a smear.
They could help by moving the car-catchers (armco) a few feet away from the nearside lane/hard shoulder to provide a grassy, soggy, sinking refuge - at least somewhere you could bump a car on the starter to. Of course, modern cars probably can't be bumped on the starter in gear because the electronics/slushbox will say "no".. I've never tried, anyone know?
Reality is, a smart motorway cant be a worse place to break down than a dual carriageway way or fast A road?
Fast A-road you can
sometimes at least get the car onto the verge.. not always - in the flatlands that usually means sinking into a drainage ditch, or arguing with a dry stone wall in the Cotswolds, or a hedge in Darzet.. OK, I'll revise that to "rarely" you might be able to get off the road
