This blog entry (Link below.) is by Dr. Bryce Anderson, PhD in Engineering. He makes his living, at least in part, by doing accident site reconstruction. He has testified in several cases, and is one of the smartest people I know. The information at his blog site can be used by almost anybody on almost any make of car. There is an old saying that goes it is sometimes better to be lucky than good. It is also good and lucky, if you know people smarter than you who are willing to share their knowledge. http://tinyurl.com/yjwwxbe.
