This implies I was giving less blame to those folks. I'm not taking away any responsibility from anyone for dangerous behavior. However, especially with how highly visible lights are on modern vehicles, it is silly to not realize any situation that at all inhibits visibility will benefit from extra signaling.
As I said down thread, I think I can logically and in full conscious support both of those statements. :)
So, yes, folks that are being negligent deserve the blame in wrecks they cause. However, signaling benefits everyone. Including folks driving in fog/rain/night/whatever.
