> why are we not advocating for people being mandated to wear them while in an automobile as well as on bicycles. While I don't know how effective they are, cars already have a safety system: airbags. Cars are also built to rigorous safety standards. As for why pedestrians aren't mandated to wear them, they have infrastructure in place to protect them from cars: traffic laws, sidewalk/street separation, and crossing lights. Cyclists on the other hand are usually riding directly in the streets or in poor excuses for bike lanes.
