never tested mileage at 55, but basically you gain 10 hours of your life back per year by going 75 instead of 65, at an additional cost of 1 more tank of gas, so at say, 5 bucks a gallon, about 60 bucks. so you gain more of your life, every year, at an additional cost of ~ $6 dollars an hour. worth it?
I've been looking at it this way for a long time now. Time is money and I could give a fuck how much gas I waste on the way there. Most of the time I'm having fun anyhow, so it's more like a hobby than just driving, which for me helps justify the cost.
