Picture the crumpled wreck of an automobile sitting in the bay of an auto body repair Salt Lake City shop. The question is: what needs to happen to transform this wreck back into the fully functional vehicle it was before the accident? Well, the first thing that must happen to accomplish this intention is that all the damage must be fully assessed. Once the damage has been fully assessed a plan of repairs must be mad because the order in which the repairs are made will depend on many factors most notably including the spatial relationships between the parts requiring repairs as well as the relative importance of the repairs.
Picture the distorted hulk of the automobile resting in the garage of an auto body Salt Lake City shop. What was the series of events that led to this car being in its present location? What could have been done to prevent this accident from happening in the first place? Would it be enough for the driver to have pulled out of his driveway ten minutes later than the time he actually pulled out? Of course the answer to this question can never be known with certainty because in the time line in which we live (at least for the purposes of this mental image) that is not how the events unfolded.
Now picture a fully repaired car emerging from the bay of the collision repair Salt Lake City shop appearing as if it is good as new. From the appearances of the car it is hard to tell that it was ever damaged in the not too distant past. This is the goal of the auto body repair shop. That is, to make the present reality seem as if the accident never happened. In this reality, the car owner takes his car home and goes about his daily business just as he did the day before the accident.
