Small/light people have on several occasions been killed by the sudden inflation of an airbag, damaging their necks. These happened in a car that was struck at a fairly low speed. So...there is ALWAYS a counter-argument. But literally thousands of people are alive today because of airbags.
When the Helmet law was passed in California, the Harley riders began wearing the skullcap "minimum" DOT helmet, with no chin protection. I actually read some of them saying if their chin hit the pavement, they would rather go through chin reconstruction surgery, than take the risk of hitting the chin guard of a helmet and having their skull separated from their spine...I've NEVER heard of a skull separation due to a helmet chin-strike. But, if somebody found a record of an incident like that, it would be one in 100,000 incidents of a biker surviving because of a helmet.
Heads HAVE separated, but on an impact that hard, the lack of a chin-guard helmet and cushioning the impact with your face-bones is NOT going to help you live.
