It's just one of very many indicators. Actually, minor compared to the pedaling style and degree of visible wobble. I was just throwing it out as a possible explanation for the purported effect observed in this study. Like most factors, I expect there to be exceptions to the rule.
Additionally, regardless of whether helmet-wearing follows a general correlation with ability to not fall over into traffic, do you have any comments on the possibility that the average driver might unconsciously perceive that?
