That’s because safety is a dirty word and when you try to tell people to be responsible whether bike, gun or otherwise and take proper precautions you get crucified and told to my your own business as this is America and one is free to do whatever he wants no matter how reckless it may be.
Nobody likes to be told to wear their seatbelt, wear their helmet, have to take classes to own certain firearms or have to have your firearms locked and out of reach. It’s seldom done when it’s mandatory, and you can bet it’s almost never done when there is no law for it. It still freaks me out going to other states and seeing people ride without a helmet especially after the giant gouges (sp?) in my helmets from rocks and debree hitting it.
