I think the trucking industry would disagree. Michigan sets the speed limit on their Interstates at 60 mph knowing that most company owned semi's are governed at 62. They write thousands of tickets for one or two miles over the limit. Michigan is notorious for this.
I was thinking more passenger vehicles than commercial vehicles, but you do have a point. That’s mostly the state police motor carrier division which does have a reputation for being kind of dick-ish.
