I don't use navigation, almost ever, after the first place I go somewhere. Therefore, the main battery estimator is just wrong. If it actually worked, as soon as you got to highway speeds you would see it half. Hiding the real estimation behind the navigation tool is cowardly
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.
The distance left in the tank is closer to the Tesla's more accurate estimate because it's constantly adjusting based on both your current gas level as well as your current energy efficiency. It may not accurately convey the distance available at the start of a trip but you're going to know well ahead of time if you're burn rate is too high. If the non-navigation distance estimate in a Tesla is always padded you could find out well after it's too late to make it to your destination or a charging station.
I wonder if anyone has actually objectively measured accuracy of various car models under various driving patterns. It seems plausible to me that everyone just thinks their ICE car is more accurate because 1) gas stations are literally everywhere so there is never “range anxiety” and 2) no one routinely lets their gas car get close to empty anyway.

How is that different from what Tesla does.

How is that different from what Tesla does.
It shows you current battery percentage, it shows you live on the default screen what its discharge rate is, it also tells you in a side screen what driving habits are consuming extra energy from baseline and percentages from doing things like driving over 70 mpg, air conditioning, altitude changes.
So what exactly is an ICE car doing better.
Last time I checked, my fuel gauge wasn't telling me about the 15% drop in engine efficiency from going to high altitude areas. Funnily enough, the Tesla showed a large increase in energy use due to going up a slop, but otherwise is not affected by the drop in air density.
