The article states that it's intended to reduce nitrogen compound emissions, not carbon. And there are loads of studies out there which prove that to increase overall traffic throughput a reduced peak limit improves average speeds, it's the whole principle of smart motorways as it reduces or eliminates the standing wave effect.

Could it be that you don't like this move because you like to drive fast on motorways?


I simply dont believe those studies. I regulalry use a so called Smart motorway on the way to and from the marina and it regularly snarls up as soon as they impose the limits. I have yet to see traffic flowing at anything like the 40mph limit regularly imposed. 20mph is more likely. But as soos as we get to the end of this speed limit and back to 70, the traffic spreads out and starts flowing.

If these studies were correct then stopping traffic altogether would increase traffic flow.
