That’s because fuel has far more energy density than batteries. Yet ICE cars still underestimate mileage.

On YouTube some guys did the experiment: driving and measuring mileage after fuel gauge dropped to empty and computer started to complain about fuel. They got about 40 miles.

This is because most vehicles have a “reserve” of 1.5 gallons. So even when the gauge hits E you still have about 1.5 gallons at current MPG to make it gas station. This is get drivers to refuel sooner and not run the fuel pump dry which can cause major damage and be expensive to repair.

Yes. Many things lie to us because we can't handle the truth. Maybe they are right? I would hope for a different world.

Isn't that by design? Some law requiring that computer needs to warn you about low fuel level while you still have enough of it to get to the nearest gas station?
