Is it really that difficult? won’t that just require a pressure sensor at the bottom of the tank?

To get real liters, they would have to calibrate every level sensor to the specific tank it’s in, because they’re all different shapes. Also, fuel sloshes around. By using a single threshold, and measuring fuel consumption rate, it’s easy to approximate distance remaining, but even that fluctuates all over the place. Then they can reuse the same equipment across multiple models for a generic sensor, which is much cheaper.
