Anyone not breaking the speed limit on a major highway is a rolling roadblock and a danger to other drivers on the road. Current highway speed limits are grossly inappropriate to modern vehicles and common driving habits, and the only reason I can think of why they have not been raised is that low speed limits produce revenue for state/local governments.

Back during the gas shortage in the 70's, speed limits were dropped from 70 to 55 to save fuel. After the shortage, they all jumped on the "55 Saves Lives" bandwagon to divert attention that they weren't raising the speed limit back again. But yeah, bottom line, most all roads are built for higher speeds but if the county or state can ticket more folks then they'll not raise the speed.
