From that article
“In March, the government published a report which found that "in most ways smart motorways are as safe as, or safer than, conventional ones", the agency added.”
In the Same period how many serious or fatal accidents have occurred on non ‘smart’ motorways?
It’s a bit like the same arguments people make against self driving cars, their is one incident where a driver has a nap in self drive modes a lorry pulls across in front of the car and the system doesn’t pick up on it in time to prevent the accident. Is it the fault of the self driving car or is it the fault of the lorry pulling across? Should the car be blamed when the driver is a sleep.
Should a motorway be blamed in a situation when a lorry driver is being distracted or when drivers stop for no good reason in a live lane ?
