Okay, good thought, but if you get in that situation you aren't going to get very far unless you are conscious. And if you want to avoid smashing your head into the windshield, which would keep you conscious, you better be strapped in. Of course, there is the understandable disregard for the law that always exists. A law that forces individuals to keep safe is a pity. Most laws like that don't work.
Human beings do as they wish.
Strapping on a seatbelt is a personal decision. The law obviously does not work in compelling people to use theirs. The ones who are willing to take an extra couple of seconds to buckle up do it because they want to, not because somebody else said they must. What hits home is people's ignorance and avoidance of raw facts. Facts prove time and time again that a seatbelt will save your life.
