In my ICE car, if I drive around the town getting 28mpg, the "range" trends downwards to reflect the poor efficiency, while if I drive a certain route where I get 42mpg, the "range" meter will reflect that. It uses a quite long rolling average Tesla COULD do that, but they don't on the main display because basing it on real data instead of garbage EPA data would produce a more conservative number and that would be harder to sell. In my ICE car, all the places I can see range remaining have the same exact number, because doing anything else would be stupid and confusing.
