No reason it has to show the EPA range. My family’s Subaru has “learned” that it lives in the mountains and the range estimates reflect that. And I’m pretty sure it’s a simply looking at what kind of gas mileage it got recently. When we have kayaks on top of the car, it readjusts the mileage estimates down pretty quickly.

All these comments about ICE vehicles being the same ignore that when ICE vehicles have estimates to empty, they take basic steps to try to get the estimate correct.
