UK delays more all-lane smart motorways for five years https://www.bbc.co.uk/news/business-59956911

I can’t think of anything worse. What sort of desk bound complete nobhead came up with this gem?

Never understood this. How can it possibly be safe to have a Motorway without a dedicated hard shoulder? Human error and technology can't react fast enough to shut down an entire lane when a car is in trouble. It's been nothing more than a money saving exercise at the expense of human lives.

Aren't smart motorways no different to dual carriageways as in multi lane, no hard shoulder and traffic travelling at 70Mph.

While I don't have a view either way on them I don't quite understand the difference between a motorway without a hard shoulder or a dual carriageway. Well apart from motorways have a few more lanes. But Same potential out comes if a breakdown ect. Maybe worse on dual carriageway as normally no matrix signs.

I might be wrong, but I’m used to seeing dual carriageways with traffic lights on them, roads turning off them, roundabouts, lay-bys, houses even… but motorways generally having a lot more faster moving traffic where drivers aren’t expecting to slow down for the next set of lights, or the person in front of them turning off onto a residential street.

Oh ok not seen dual carriageways like that very often. I use the A12, A34, A303 a lot and they are very fast rounds with no hard shoulders, very few laybys and certainly no traffic lights..

So guess there is a mixture of dual carriageways around the country where motorways are pretty much the same.

Having used smart motorways I can see the benefits but the rescue areas are too far apart and unless you have a rapid response unit that can lay traffic cones within 1 minute of a breakdown then they need to do more analysis and engage with motoring public.
