You are grossly misrepresenting the argument. It is about 30mph inside cities. Which is a great idea, not just for saving lives but for substantially increasing quality of life of everyone living there. The greatest cause of noise in cities is traffic. Setting a strict speed limit would substantially reduce this. (Also side benefits like better air quality and so on) And traffic would actually flow better, so you might not even reach your destination that much later. You can be protect your individual freedom at all cost and treat everything as a zero sum game or you can bee cooperative and help build a better world for everyone by compromising a bit.
