The above is not meant to insult those "non-pilots" who are experts in their fields of aviation incident and accident investigation and at least have an understanding of what is being explained about the differences between flight plans and clearances. Unfortunately, their cause is not helped by the "non-pilots" who are trying to persuade us that they somehow know better than us how to fly a clearance
If we leave out the judicial aspects of this discussion, then the only thing that counts is the resulting recommendations to prevent future accidents with similar causal factors. This will require uniformity or better understanding within the aviation infrastructure. Driving on the road on the ground has nothing to do with this.
