Sure, they claim that. With what actual details? If you dig into that there are all sorts of details that get glossed over because they don't think about it, it is just what "has to be done". With a big helping of "this is how I've done things before with the old tool, so if the new tool doesn't work the same way then it can't possibly achieve the
actual underlying goal".
With an Model S 85. Even brand new that would be very tight. And now with an LR why aren't you doing it? Where exactly do you live? If you can't drive even all the way from say Katy to the Italy SC well above posted limit with your LR that's serious weirdness. Personally I'd probably still stop at Waco for a little bump and stretch my legs, because you have to stop somewhere (same as ICE) and sets the stage for getting around in town. And the value, the quality of life and
actual trip time, of a leg stretch has really been brought home to me over the last couple years.
Or you're talking something like Pearland and Flower Mound are the two "required" ends?
Of course there is a certain distance window where there's a discontinuity if you focus
only on trips and narrow the evaluation window to exclude fueling at the ends. But longer and the apparent ICE advantage disappears, shorter and it isn't there either, and as
@EnrgyNDpndnce laid out if you look at overall vehicle usage it turns on its head.
EDIT: And the thriving existence of Bucee's in Martinville underscores just how much this doesn't actually happen with ICE.
One of our former ICE vehicles had a huge tank range. 2012 Camry Hybrid, something crazy like 600 miles if you drove near posted limits. I don't miss it for driving between those two cities. Not. One. Bit.
Now if I was in a much colder climate, or I regularly towed a larger trailer, that'd be something different.
