I think whether or not to wear a bicycle helmet comes mainly down to risk assessment. I can understand how one decides not to wear one based on the risk factors outlined in this study.
And with the risk factor being only 0.18 higher, bike helmets sure don't seem to be very effective when it comes to car-bike accidents.
That's actually a pretty big reduction in risk when you consider that these are severe injuries. But for the actual risk multiply by the chance that it occurs, which is extremely small there. 150 cyclists in a billion kilometers, not worth the worry
