So I've been reading alot of articles about how people are testing their efficiency in their cars and alot of the time they talk in terms of kwph. As a first time EV owner (soon to be with a MY), can someone dumb down how to better understand how I can tell if my driving is efficient with a Tesla and how to determine range based on that driving by looking at the graphs in the car? Obviously, I'm just used to a gas car where it has a tank gauge and usually a range estimate and I go off of that, but from what I can tell, alot of people go based on battery % or kwph. Sorry if this a dumb post, but I just need to better understand because the numbers people are tossing out are all over the place.
