While all of this is true, I think Tesla made a bit of a user interface mistake by displaying charge in “rated miles” rather than percentage on the dashboard. The rated charge figure can be misleading for people who don’t understand how EVs work, and that the energy per mile can vary by as much as 2-3x depending on weather, grade, etc., so your “200 miles to empty” range might really only be 100 or 65 miles. I think it would be less confusing if it was always shown in percent, or if it showed the “effective range” based on the last 15-30 miles (the way the energy app on the main screen does).
This is exactly why we need Tesla to create a route aware miles remaining estimate. If you’re making any long trip, you plug in the destination and Tesla uses map data for grade and elevation, and weather forecasts along the route to more accurately predict the miles remaining. For little trips around town or your commute, when you’re less apt to use navigation, the estimates won’t be as accurate, but that’s when range isn’t a concern. No reason why Tesla can’t implement this technology.
