"driving" in the left lane. YES it's illegal.
FL law will now ticket you for not getting out of the left lane.

IIRC, here in PA you can be ticketed for staying in the left lane for over 2 miles if you are able to move into the right lane safely. I've never worried about the exact distance because when not towing I often change lanes and when towing, I try to stay at 60-65mph on the interstates in the right lane. I prefer to not change lanes much while towing a TT.
