I get that some people art not interested in the minutiae, but there is a whole category of inefficiency outside the normal range of inefficient things people do with Teslas.
I get that there is running your heater, I get that there is vampire drain. But ask any hypermiler and you will learn there are many ways to travel the same circuit (same distance, same elevation change, same average speed etc) and the hypermiler can do it more efficiently simply by BEING PATIENT ABOUT GETTING TO A CERTAIN TARGET SPEED. ie never use large amounts of acceleration. Ie don't make the temporary power usage too high at any given moment. Ie never withdraw energy from the pack at a high rate. Ie dont cause cells to expend energy too quickly. Ie don't incur (unmetered, but real) "resistive losses" *within the pack* due to high current flows.
Ie use chill mode and don't stomp on the go pedal.
If you want to be efficient.
I dont: I mash the thing. I'm not saying what you should or shouldn't do. I'm just saying chill mode efficiency gains are real.
