The point is that ordinary commuter cycling in normal weather on flat, clean roads is a lot less dangerous than standing around while people throw bricks at your head. And there's a health tradeoff between the exercise benefits of physical activity and the risk of injury. Convincing people that cycling is so dangerous (like people throwing bricks at your head) that you need to wear some goofy-looking, uncomfortable contraption dissuades them from getting the exercise and the fun of cycling around their neighborhood. |

This is true until you fall off the bike and your head hits the pavement. Then having a brick thrown at your head might well be safer. It's only the lower expected probability of having one event occur than the other that gives the illusion that it's safe. But if you ride a bike everyday, even in the safest of conditions, your odds of having an accident at some point are actually pretty high given all of the variables involved. So you should wear a helmet every time you ride with the assumption that it will do nothing for you if you don't have an accident.
