Great story about the helmet mirror. I became a mirror convert 10 years ago, which made me into an obnoxious mirror evangelist, but the truth is I now hate riding without it, and I even miss it when walking and worrying about being right-hooked.
The comment about tribalism is painfully true, which is why I worry about the vior dire jury selection process in vehicular manslaughter cases, having seen too many bicyclists thrown off of panels. The curse of tribalism infects our politics, our religion, and our behaviour in public.
