Just a safe driving tip for everyone today as I just got back from a 6 hr round trip road trip.  I have sort of a pet peeve as I drive on the interstate:  driving slow in the passing lane.  Number one, this is the suggestion of the Transportation Department in most states.  You will almost always see white signs that state "Slower Traffic Keep Right".  You should utilize the left lane to pass someone going slower than you.  It is not a cruising lane as the right lane is.

What are your driving pet peeves?  Post them in the comments.
