After going through the forum, I'm definitely seeing a lot of people saying they would wear them, but only if it were "cool". Where I used to race in Colorado, many people on laser's would wear helmets.
I never considered wearing one before (in spit of hitting my head all the time on the boom), but since they are so cheap, I will be getting one this season for the windier days this summer. I just had a car accident earlier this week and realized how easy it is to injure your head. And like someone basically said above, young people have stuff to break in there (I'm 21, in college).
Hopefully I can start a bit of a fashion statement and make it cool
