As has been pointed out before, none of this applies to most people. And certainly none of it applies when anybody gets into a rental car.
You’re busy arguing something equivalent to how you know what a properly aspirated engine sounds like, and you know perfectly well how to use a manual choke, so why do these new-fangled have cars have automatic chokes? They’re suboptimal!
And while, certainly, as has been mentioned, a Tesla will route your whole 1000-mile trip, nobody follows exactly what it says. When I’m on a road trip, I route at most a couple of superchargers down the road. And things change every time I change my mind about what roadside attractions to visit and whether to eat lunch at a particular place, or if I prefer an alternate route, or whatever. Things change, but at all times the car knows where you say you want to go and how much juice is left, and how fast you’ve been using what you’ve got. So it can tell you well in advance if you’re attempting something stupid.
And, of course, nothing stops you from doing your own planning. And pretty much everybody does to some degree, but the car provides back-up confirmation that it will work, and provides safe and sane alternatives if you don’t want to or can’t plan.
Arguing against a software feature that provides safety and convenience seems really strange.
