I also sympathize with bar10dah and with you, kamsmart. I don't like getting behind people travelling 45 mph on the interstate either. And the person travelling 20 on the highway, if caught, would likely get a ticket for obstructing the flow of traffic, I believe.

But I would rather see someone driving 45 on the interstate than someone plowing past me at 90. I feel that the latter driver is more of a hazard to me than the 45 driver.

Kamsmart, I have to take issue with your statement that driving 45 mph on the interstate is hazardous. If it were hazardous, the states would not set the minimum speed there. IMO it is the people who are impatiently trying to dodge around that driver, or who come up behind that person either exceeding the speed limit or not watching road conditions that cause the hazard. Just my opinion.
