Those are good questions that you pose, and for what we all know here, we will never have an answer most likely. I do agree on the last statement as well, the modification of the road test would only go so far. Youre still going to have your idiots who drive without one, or still drive recklessly in poor situations(Im not condemning anybody with that statement, as I, as well as 99% of the people out there have driven recklessly at one time or another). Its just a measure to maybe make it a little more of a test to prove driver ability, especially in handling situations and what not. Its never going to 100% solve the problem, and my thoughts may not be the way to do it, but In the end somebody will come around with something that will help to reduce the issues. I guess only time will tell
