It seems lots of people are confusing Smart Motorways with All Lane Running Motorways. A Smart Motorway will have traffic management systems such as variable speed limits but it may still have a continuous hard shoulder e.g. parts of the M25. Some Smart Motorways also have All Lane Running where the hard shoulder has become a running lane with emergency refuge areas e.g. parts of the M3. The More or Less radio programme mentioned above is well worth listening to.
Seems that the data suggests they are safer than you might think - for a multitude of reasons:
More or Less - Third wave fears, smart motorways and bra sizes - BBC Sounds
