I have heard the freedom argument used by people who don’t think there should be mandatory seat belt laws. As someone who grew up with both mandatory seat belt and helmet laws (Australia) I just don’t get it. If you reduce the number of injuries then you help keep insurance premiums down. If it’s a free for all and people are getting injured left, right and center then the premiums go up to cover the insurance industries rising costs.
Plus from a personal point of view I don’t want to ever see anyone die in front of me just because they couldn’t be bothered to wear a seat belt or a helmet.
