This is one of the things that drives me absolutely nuts on a daily basis. The left lane in the U.S. is for passing. If you are not passing, then you should not be in the left lane. It's that simple. Some states even have signs posted that say something like, "Stay In Right Lane, Except To Pass". How freaking difficult is that to understand? People who can't follow this simple rule are dumb ass, idiotic nobs.
Thank you.
Easy. Bat. So many uses.
