So the implication is it's getting it's data from local weather stations and not from the vehicle itself, no?

If anyone know, I'd be interested in the more details and what led to that decision.

It can’t know you are planning to drive over a mountain unless you put that in the nav system.

He did chart a trip.

Using the trip counter isn't the same as entering the destination in navigation. If you tell navigation your destination it will tell you if you're going to make it or not. If you start driving like a madman halfway through it will reevaluate and start navigating you to a charger. I rented one for a week and took it up into the mountains, far from a charger. It was scary, but we made it back with 17% charge once I stopped passing everyone every time there was a dotted line.

I'm aware - pretty sure they did chart the trip in autopilot though from my reading. Telling the autopilot system you are headed to a supercharger also starts pre-warming the battery.

That's a bit annoying to me to be honest. It's a cool feature, but sometimes I want to plan out a trip without having to prewarm, or I want to prewarm without having to navigate. I can imagine why it's automatic instead of manual (imagine if someone prewarmed their battery but forgot to charge or something) but it'd be a nice "advanced" thing to have.

I kinda agree. But why would you want to go to a supercharger and not pre-warm? It already doesn't pre-warm if it thinks it will prevent you from making it. I can't think of any other reason.

Wanting to prewarm without planning a trip I understand. It would be use to be able to prwarm for regular charging or non-supercharger charging too.
