How does Preconditioning work?

So, ultimately, they are pumping heat from your body into the battery

If the cabin needs cooling, yes. But when I was doing this, the cabin required heating, so my car was pumping heat from the atmosphere into both the cabin and the battery.

kinda has to, since the heat has to come from somewhere. That's true even MS/X where there is a dedicated battery heater (dont know if the newer ones now use the same trick as the 3/Y).

I've never bothered, but it you are very careful about steady driving you might even be able to see the change on the energy screen, though I doubt it will be much of a difference. (Remember that the motors are always generating some heat even when normal.)

you can definately see it on the energy screen - and it's not insignificant. I noticed yesterday, 70 miles of range used, 17 of those were for supercharger precondition.

Now what really drives me nuts is the term “Near-miss”. When two planes ALMOST collide, that’s a “near-hit” a near-miss means they almost missed, and actually collided…

But what do you think a "far-miss" might be?
