Wearing a seat belt does not make you invincible. You can still get hurt or killed while wearing your seat belt. But wearing them has proven to be safer than driving without them. You are much less likely to be killed in a car wreck if you are wearing a seat belt. You are much less likely to get seriously injured if you are wearing one. So why not take the safer way? Why not go the way that has been proven to result in fewer deaths? You do want to live, don't you?
