I drive just as fast as the traffic and road will allow me if I'm feeling confident the law ain't around. However, my top cruise control speed is usually around 80-82. Trucks wound up pretty tight at that speed. I could use one more gear. Now if I'm not pulling a trailer I may set the cruise at 85. I'm an alert driver but a fast one I guess. I don't care for listening to the radio especially in town. This aggravates my wife. I like to listen to my vehicle.
