Reserve is big. That gives more safety, but has also a technical reason:


The electric fuel pump is located inside the tank, and is cooled by the surrounding fuel. So, having always some fuel left in the tank protects the fuel pump, and due to the big reserve, that is given even if the driver doesn't think about the needed components to keep the car driving.
Of course you can drive the tank empty. Reserve should be somewhere near 100km even in an automatic version of a Daihatsu.
I stopped doing so, after I learned, what a new fuel pump costed... Its cheaper to fill up a bit erarlier in the long run, and it is good to know that in an emergency there is plenty of reserve fuel before you run it dry in the middle of nowhere. From then on, I took it as a built-in reserve canister. The car is small enough, even without spare fuel in the quite small thrunk.
