> That's why we have airbags, because no one will wear a helmet in their car. Airbags are much superior to helmets, allowing for deceleration to occur over ~10 inches rather than over the ~2 inches provided by a helmet. That allows for a much smaller force to be applied to slowing the head. It would be a massive reduction in safety to replace airbags with helmets. Rather, we (still) use helmets because motorcyclists can't take advantage of airbags.
