To the original post, unfortunately, blinking seems to be a lost art. Too bad. I always thought that being alerted to anything of concern up ahead was good driving. Many states consider it's illegal, but I never let that stop me. While I don't condone speeding per se, I do consider driving courtesy as a high priority. Driving slow in the passing lane is far more dangerous which is the norm out here in the west. If you can alert the oncoming traffic to anything that requires attention, you should do so.
