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.
