I’m not a fan of so- called Smart motorways- because as they are busy ( potentially) saving the environment - I’m getting killed because there is no hard shoulder to pull on to in an emergency.
The way that the 50/60 signs are randomly switched on/off on a clear afternoon with little traffic on the M5/M4- cannot have anything to do with traffic flow- more cash flow- into the local coffers.
Exactly how many times have you died on a smart motorway because of the lack of hard shoulder?
