As long as they do not end up with true "smart motorways" rather than variable speed limits which is what they actually have.
Smart motorways do dumb things such as allow the hard shoulder to become a running lane during heavy flow - thus resulting in a number of deaths because people in broken down vehicles have no safe refuge from which to access the emergency telephone network along the hard shoulder.
But you just call them from your car? There are signs on the harbour bridge reminding people to stay in the car, they will see you on the cameras and send a cop out to see what the problem is. Would be crazy to get out of the car without a vehicle with flashing lights to block traffic.
Google it. It matters not where you are when a truck drives into the back of the broken down car at speed in the fog.
