Can't imagine how author pulls out of his ass the notion that speed limits are less impinging on liberty than seat belts. I also find it hard to believe author is not being disingenuous stating "repercussions of not wearing seat belts only affect the decision maker". The last couple paragraphs are opinions stated as facts and very much want the reader to agree with them I can't help but feel the whole article/data was just a means for author to push his opinion.
