Why? The flight manual and a stick, verified by experience, work very
well.

Not great for real time info in-flight, though. Particularly the
stick.

Inaccurate gauges are not the cause of the problem.

No, but accurate gauges might help solve it.

A accurate fuel gauge would be very helpful. There are many things that can
throw off fuel consumption calculations.

I've proposed to homebuilders that an infrared CCTV camera with IR LED
illumination looking through a small window into the tanks which contain a
simple stick scale showing remaining fuel. There's something comforting
about the idea of actually seeing an image of the remaining fuel.
Fortunately, solid state TV is very cheap these days.
