As someone who frequently travels the motorways of the UK I’d like to add an observation on the Smart Motorways issue.
Often when I’m on a motorway, smart or ordinary, the inner lanes are often empty but the middle and outer ones are busy. It therefore seems illogical that when converting to a ‘Smart’ motorway or widening in general it always seems that they add an extra inner lane. Why? The existing one is hardy used. Wouldn’t it make more sense to create an extra outer lane so that we can get past all the drivers hogging the the current middle and outside lanes?
Just a thought, mind how you go.
