Do the same, less inaccurate thing that every single other car maker has always done and give more accurate range estimations? Something Tesla already does in the route planner, and also show they know how to do as the battery meter gets closer to empty, when they switch out their estimation for more accurate ones?
This isn't difficult. Tesla is not required to use the EPA range estimation figures to do any range estimation internally, it's literally only something that goes on the window sticker. Tesla instead chose to design their range display to do something that no other automaker did, and use a KNOWN OVERESTIMATOR as their methodology for range estimation.
Nobody else has to set up these call centers because nobody else chose to set up their range meters in such a way to mislead customers. It's really that simple.
