Not shocked about that, you are kind of nitpicking, but, nevertheless, it's something that Tesla could improve. Like the Boring Company says, "if there's something we could do better, we ask the public to let us know and we will try to improve". Tesla should do that too, wouldn't it be fun if Tesla had a public RFE list where you could vote for features if you currently own a Tesla and Tesla could prioritize/schedule and respond/comment/suggest workarounds. In an ideal world, yes, I agree. But would you drive an ICE with 8 miles left? Nope, because variations in inclination of the car might cause that petrol (if very low) cannot be successfully delivered to the engine and your journey ends. I believe estimating the final miles of an electric car could be similar, very granular and very unpredictable. Anyways, I agree that it probably can technically be solved, to give a coarse underestimate of the remaining mileage, after reaching a certain level, say after 30 miles remaining. It would simply be very kind for the stupid human driver who is anyways lazy and distracted and trying to push the limits at the end of his/her journey.
