Since the implementation of motorways, there has always been a hard shoulder which served several purposes. It is a safe zone for a vehicle to use if there's a mechanical problem, if there is a sudden emergency and more so, it was a clear lane for emergency services to use.
Since the implementation of smart motorways, this lane has become a live lane and if the unforseen happens, you are stranded in what is now a death trap and also delaying emergency vehicles attending an incident.
