I watched a programme about smart motorways a month or so ago, and resolved never to drive on one. It was frightening; cameras that are supposed to tell the control centre instantly when a breakdown occurs were pointed into the meadows either side of the road, or at the sky, some didn't work, and several people told horrific tales about their experiences. Other drivers involved in breakdown incidents didn't have an opportunity to tell their stories as they had died trying to get out of the way of fast traffic - one man was killed trying to squeeze out of his van, parked as far up the verge as he could, and he was hit by several other vehicles.
