I am actually noticing people sitting more at 50MPH on the main roads and 60 on the duals on the way to work lately compared to the last 3 years - mostly driving to the commercial vehicle speed limits I'm noticing a lot less people rapidly closing and sitting on my tail. Though I had an annoying tailgater couple of days ago - absolutely no excuse for it - in the end they got the hint and overtook me (I think they were trying to "hyper mile" in my slipstream).
