C'mon Closetbiker, be logical or at least avoid generalizations like "Understand, or remember as this has been shown to you time and again, that riding a bike carries no more risk of head injury than walking down the street."

We're talking risk assessment here. Do I base my risk assessment of wearing a helmet on population basis statistics or my own given circumstances?

I'm curious what RazrSktr thinks would be an appropriate speed to travel down my road. In other words, at what speed would my risk of head injury be equivalent to walking down the same street?

For example, I'll do a 50 + mile ride with an elevation gain of about 5000'. I'll like wise be descending a similar amount. How slow does RazrSktr suggest that road cyclists reduce their descent speeds to in order to avoid collisions and accidents? And, if I slow to his suggested speed, does that still mean I should do these rides without a helmet? You guys keep telling me how safe bicycling is please convince me so that I can take this stupid piece of plastic off my head if it's that unnecessary.

And, like Sean Gordon, I too ride in NYC. Should I not bother to wear a helmet as I make my way through the traffic in that city? If anywhere I've considered wearing a helmet while walking down a street it's Manhattan. I've had ice fall off of buildings and scare the beejeezus out of me. Who knows what else could fall from one of those buildings.

C'mon, be reasonable. Tell me how safe I am riding all the places I ride and how I don't need a helmet when I do.
