That's the odd thing about living in small town West Virginia.
People do signal but they seem to have no idea what "right of way" means. But in a good way
When you meet another car at a 4 way intersection, first they signal then they smile and wave the other guy through whether or not they have the right of way.
It's when we travel that people start acting like jerks.
We were traveling in Alexandria Virginia to visit with my wife's parents and I was complaining about people changing lanes without signaling. My wife reminded me that in Virginia, if you signal a lane change, that just tells the jerk in the other lane to speed up and cut you off.
"Yeah, well I'm driving a full size Dodge Ram and I signal."
And yes, I've had these jerks blowing their horns at me when I moved over anyway.
