No, I'd say it's still pretty obvious. Without knowing what percentage of accidents are from car strikes, the latter may not matter. From what I've read, in most city conditions, you're far more likely to get hit by someone opening their door, or bump into something when avoiding people or slow moving cars. In both cases a helmet is pretty helpful.

Maybe someone should design a helmet that looks like it's not a helmet somehow. Maybe it's disguised as a beehive hairdo.
