You are most welcome.
There is only one bone I have to pick with people who make "slower traffic keep right", "the left lane is for passing", and "the flow of traffic" type of comments. That is in the case of a commercial vehicle travelling 65mph passing another travelling 63mph. This is a perfectly valid use of the passing lanes on a highway, unless signs or local rules indicate otherwise (e.g. no trucks this lane). In this case, 65mph is the flow of traffic in that area and everyone behind should be aware that they are travelling faster than the flow of traffic until the pass has completed.
