I see the concept of 'smart motorways' as a triumph of theory over practicality.
I am sure that some suits turned up at the MOT with a computer mockup of a smart motorway system and a vast sheaf of statistics to demonstrate the effectiveness of the new system - and sold the entire nonsense and got it built.
Of course, as is so often the case, reality turned out to be very different.
The notion that monitoring would ensure that lanes were closed when a breakdown / accident occurred never happened because, with the exception of a bit of the M25, no other SM has the monitoring hardware in place.
That system also presupposes that each and every motorist will adhere to the advice that a lane ahead is closed, and move out of it - evidence naturally proves that this is not the case.
What we have now is a death trap system with system-thwarting breakdowns all day every day unmonitored and causing further accidents and delays, adding to the existing horrendous death toll which is only set to rise.
The simple fact that the AA will not allow its mechanics to attend on 'smart motorways' should send a clear message to the MOT that this is an expensive disaster, and money and lives should be saved now by abandoning it and returning to the old system.
Failing that - make Grant Schapps and the team responsible for this disaster attend each and every victim's funeral in person, until the impact of their folly hits home.
