My driver’s safety course instructor was a police sergeant with over 20 years on the force. He was also in charge of accident reconstruction, and trained officers from around the region in it. So I was beyond blown away when he said, regarding the three-second following distance that, “Any two passenger cars traveling on the same surface at the same speed will be able to stop in the same distance.” When the class pushed him, he said that repeated tests and studies had shown that no other factors mattered, apart from identical speed and road conditions. A large SUV, he said, will have the same stopping distance as a sports car. He then said only reason a vehicle would have a longer stopping distance were if it were a large commercial vehicle. Because I forgot, physics only applies if you have a CDL.

How the hell did you get to be an accident reconstructionist if you believe something that is not only incorrect, but physical impossible?
