I don't usually wear a bike helmet. Does that make me an idiot?
This is the video I didn't want to make. For a long time, I've chosen not to wear a bike helmet on my daily bike commute because I didn't feel I needed one. But people ask me about it so often that I started to doubt myself. So I decided to take a deep dive into that decision. And to do so, I enlisted some help to explore the big questions around bike safety and helmets.
This is our conversation. Big thanks to Cailynn Klingbeil for exploring this issue with me. You can find her on Twitter at https://twitter.com/cailynnk
