As far as fuel level gauges go, I think the long-distance-on-full phenomenom is largely explainable by the way the fuel gauge is constructed. It's a float, so the fuel level has to drop quite a bit before the float can move (the width of the float). In addition, if you've filled up fuel into the filler neck, there's obviously no way the float can detect that. Additionally, you really don't need to know the fuel level when you're near full do you? I think this is one thing I can live with.
