That driver was very, very lucky and won't ever do that again.
I used to cover breakdown and recovery occasionally many years ago. I didn't do it often, but I did it enough to develop a hatred of any jobs on the motorway.
I'd rock up wearing full hi-viz, in a 7.5 tonne flatbed with reflective tape on pretty much every surface of the truck, lights on, hazard warning lights on and a top of the range light bar with 4 rotating amber beacons and 2 alternating 55w red lights at the rear.
And still muppets wouldn't see you on the hard shoulder until the last second. I was lucky that the worst that ever happened was the offside mirror on the truck got smashed by someone getting too close.
