Even the very best drivers can make a mistake. Any LEO (at least in Calif) has to attend EVOC per California POST requirements in order to graduate from the Police/Sheriff academy and having been through it myself (although several years ago), it helped me learn my limitations of what I could do and not do with a car. Unfortunately your average driver doesn't go through any type of advanced training. This is not to say that advanced training will keep you from crashing, but it's a leg up.
I am always saddened to hear about someone losing their life, especially in something as senseless as high speed driving while trying to have a little fun. My prayers to his family.
