Talking down? At no point in your statement did you even mention one of the single most important factors that affects fuel economy. You made assumptions about the fuel economy not changing at all and I brought up a factor that you failed to mention which is the driving factor behind the continued rate of fuel consumption.

I've tried to be polite but now allow me to say something that maybe you can understand: If you were offended or if I hurt your feelings then you need to grow up and be an adult. You CHOSE to take offense and read between the lines so that's on you. To continue to drive this thread off topic is all you...
