For what it's worth, I like setting it as an option.  As in " I know that I can usually get 30 miles per charge". Since it will be different for everyone that seems like a sensible option.

>> Tesla was forced to come with a new name because the EPA changed how they evaluate vehicles, giving less optimistic numbers for gas mileage as well as electric efficiency and range. So Tesla called the new numbers the much more descriptive "rated range miles", while still using the "ideal range miles" as their estimate of what the range would be under the old EPA scheme.
