You are totally missing the point of speed limits first of all. They aren't there for any reason having to do with fuel economy or "best cruise speed" for your car. It's all about the upper limit of safe speed in average cars during marginal weather. Slower speeds are ALWAYS better for all cars in terms of safety! I also highly doubt your claim of 95mph being the most efficient in mpg. The wind drag is exponentially increasing as your speed increases, so you should be getting worse and worse mpg as you go faster and faster. In other words, if the speed is constant and your not braking and accelerating over and over again like in a city, you'll get the best mpg the slower you go.
Your idea of different speed limits on different types of cars is also a bit far fetched. Everyone going the same speed is much easier to manage.
