In my younger days, I was more likely to drive over the limit, and to be honest I don't think it really made much of a difference in how quickly I got anywhere, but it used a lot more fuel, was more likely to kill me and was far more stressful having to keep switching lanes to maintain those speeds. Nowadays I'm more like you described, and I prefer to just punch in the speed limit on the cruise control and enjoy my podcast/music. If the traffic ahead slows down, I slow down. I leave the outside lane to the angry BMWs.
