The is a simple test to see if the designers and politicians really think they are safe.
Get them in a small car fitted with TV cameras (so the public can watch). Ask them to stop in lane one between refuges in a normal rush hour.
The motorway operators won't be told about the test, to make sure they don't gain an unfair advantage.
Since they are stating they are the safest parts of the motorway, then they should all agree to this test.
I can guarantee not one would agree to do this.
(This is without even asking them to do it with their children in the car)
