Again off track from the original thread, but I will quickly answer your worry. At 65 MPH, I stay within the Semi's, most travel at 65 and most are governed at 65, until you enter most urban areas or your in Commifornia. In Commifornia trucks are regulated at 55 mph anywhere in the State. FWIW, when I went in to port in Long Beach Ca., picking up 40' containers for XXX trucking, I never did 55 MPH, I always ran at my governed speed of 65, I even had CHP on my ash waiting for me to clear the sheep doing 55 several times and not pull me over. Never the less I'm able to drive safely in and out of lanes. I did have one ash hole wanting to do 80 in a 65 (common in Comifornia) flashing his lights flipping me off on the 58 through tehachapi pass that had a long lane closure.
