Good question. I think /during/ a collision, statistically (studies show), they would help. Although, as with any statistic, it is not a black-and-white rule -- for example, due to the slightly wider diameter, there would be a slightly larger chance of hitting something that otherwise you would have simply grazed. But, my main original point was to consider the steps /before/ a collision, since it seems that wearing a helmet may increase the likelihood of incurring a collision. (Since cars will drive closer to you, less people will share the bike lanes, etc.)
