Just out of curiosity, Do you use an interstate of freeway in your daily driving? When my daughter lived in Valdosta, she would use interstate to get across town. I am at least thirty miles from the nearest interstate and I may not be on one from year to year. Also how fast do you drive? On my rare excursions onto an interstate I keep up with traffic. Regular state highway with a 55 limit I will traval a max of 62 if there is other traffic, if not around 53. On town and local roads around 35 to 45. I adjust accordingly as not to bother other traffic. Pisses me off when people do not drive 55 on a clear open surface. 55 is not at all fast. Modern vehicles are designed to far surpass that speed under almost any circumstance. If your vehicle or yorself are not in good enough shape to maintain 55, I suggest you find a driver!
