Thread bump - far from a clear cut case but just how much more evidence does it need that smart motorways, even when working as intended, are not a good fit (putting it mildly) for the UK:
Derek Jacobs' van was hit by another driver, who had "not been paying attention", an inquest hears.

In general though I'm seeing more and more people not paying attention as they drive, not just momentary lapses or being lulled by driving the same route time and time again but blatant irresponsible doing other activities taking attention away from the road which anyone with half a brain would realise substantially increases the risk and so on for other drivers.
