Don't misunderstand me, I'm not complaining about it. I am seriously asking about how the process is done, has it ever been reevaluated, or is this just the way it has always been and no reason to change. This was something that I wasn't aware still existed until I moved here.
In the "old" ( 1970's) days, we did this process by hand...no computers, no GPS, no calculators.
We would establish point of contact, debris drop and spread, take exact measurements from landmarks, usually telephone poles as they had a location marker, triangulate, and use these points to draw detailed charts of the accident. Weather conditions were noted, as test skids could be laid to determine approx speed prior to impact.
Accident reconstruction is not only evidence collection but physics.
You cant change the physics of cause and effect.
Sometimes there is a fault in the roadway that caused the accident, and the results from the AR report can causes road improvements, changes in the road surface, improvements in vehicle safety, changes in those factors that could have prevented an accident.
Northwestern University used to be the premier institution for learning AR. I was trained by another offer who was trained there. I still have my book and a nifty template used to calculate speed, friction factor, etc.
I enjoyed the mechanics/physics/math of Accident Reconstruction, but not the causative event.
But in this case, I doubt anything would have changed the outcome of this accident as you cant remove or fix "stupid" from the equation.
