I don't understand this - are you implying that the only way to safely drive on highways is to always maintain a follow distance equal or greater to your stopping distance? I don't think it's reasonable to prepare for the car in front of you to stop in place as though it had hit a brick wall. Instead, the safe follow distance is derived from the current speed and breaking power of the vehicle I'm operating and the vehichle that's behind me, and the distance to the vehichle behind me.
