Please read the signs....

To those who suggest that they "won't jeopardize the safety of others or my family" by trying to find a place to move over to let the waiting traffic pass, you may be doing just that. Consider this, that "road rage" does happen and it's been documented in varying degrees for decades. I would suggest that trying to justify blocking traffic by invoking the safety mantra means nothing to the wrong individual you may be holding up. When trapped behind a slower moving vehicle, I have been known to on occasion utter the phrase, "I don't mind if you want to drive slow, just don't do it in front of me". I'm not about to act upon that premise other than to wait for an opportunity to safely pass, but there are those out there in the real world that may do much more, given the right set of circumstances and conditions.
Just playing Devil's Advocate here, no offense to those who have indicated their contrarian positions.
