With all due respect, from my own personal experience I believe you are mistaken.
I was pulled over just north of Austin a few years ago. I was in an Volvo VT-770 headed SB on I-35. Everyone around me was doing at least 75 while I was doing 65 in the 2nd right lane (a travel lane). A state trooper lit me up, pulled me over, and gave me a warning for impeding the flow of traffic. In California a few years before that I was driving an '04 Freightliner Columbia on CA-99. The speed limit in that area is 65mph for non-trucks, and 55-mph for trucks. I was doing 55mph while everyone around me was doing at least 70. I was pulled over and given a ticket for impeding the flow of traffic.
EDIT: While driving truck I always stuck to the speed limit. It's only in my personal vehicles that I have a lead foot.
