As a tesla owner for several years, I find this hard to believe. 15 minutes at a 250 kw charger doesn’t even get you 50%.
I can go buy a surgery robot but that doesn’t mean I know how to use it. Just because you own a Tesla doesn’t mean you know how to road trip it effectively, or have one that can do what I literally just did. For example, an early Model S or X can only charge at 120KW no matter what charger you plug it into, ergo no, it can’t do this. But any long range or performance model 3 or Y certainly can.
Part of the reason there’s so many stops (which I prefer and so do my wife and daughter, for that matter), is that if you keep the battery’s charge level between 10 and 50% from hop to hop, you end up spending much less time at chargers in general because you’re always charging at peak or very close to it. Sitting at a charger waiting for that last 10% at like 75kw from 70% - 80% is MUCH slower than hopping on down the road and charging at near peak at the next charger.
It works, I know for a fact it works, and I brought the receipts! Here’s a few examples from my trip:
