http://www.chron.com/cs/CDA/ssistory.mpl/front/3222360 This just seems like BS. There are so many factors that contribute to safe speeds (condition of the road, traffic, type of car, etc.) that to paint it with such a broad brush is absurd. I recall reading somewhere that the vast majority of the interstate system was originally designed for 85 mph traffic. I have no idea where this was, but I'm guessing some of you (RED!) can shed some light. This is one topic that just drives me nuts. Maybe it's because I think not all rules apply to me.
