Yes! I know there will always be doubters that follow the old line. I am not the one that did the research but it has been done (by different agencies). Michigan, Arkansas, Northern Territory have repealed (as have others). Florida exempted adults. 20 States weakened their helmet laws to young riders. Israel is in the process. Ireland is discussing it. There is a strong lobby from MAG & BMF in the UK close to winning the argument. And so on! Just cause you ain't heard of it makes me think you don't know a lot about it!
Because something has been told ad infinitum does not make it correct! As for suing, that is about as fallacious as most of your other emotional argument. You may well want to wear a helmet, so please feel free to do so. I and many of my biker community prefer not to. I have covered between 10 & 15 thousand miles per year for around 45 years and half of those without a lid. The reason I have been forced to wear one at all is because of people like you. Keep the rubber side down!
