Guidance part 2

www.ebaumsworld.com/carcrash.html If you click the link you will see a rather graphic illustration of the point I made in Guidance part 1. If you haven't read Guidance part 1, then read it, then check out the video. The point I made is that you can never account for all the unknowns in life. The guy in the above video probably never had a clue that his day was really gonna suck. Newton's second law just changed the course of his life if it didn't end it. Ouch!
