It IS NOT an estimated range value. It has never been meant for estimating range. It is simply a fuel gauge. It shows the amount of energy in the car.

And it has all of the deficiencies and shortcomings of that. 50% of what? of 10 gallons? 20 gallons? 30 gallons? How big is the fuel tank? Is this an S75 or an S100? That 50% means all kinds of different things. It’s not scaled to anything.

And the other deficiencies it has are because it’s just a fullness ratio. If the battery continues to lose capacity over the years, the % gauge will still show 100%, when it’s as full as it can be, regardless of how little energy that is. So each % moves and shifts over time of how much energy it represents. It’s not consistent.
