Even for consumer devices, battery aging and capacity loss is very slow after 70%, and they are exposed to much harsher conditions than EVs (no temp control, daily full cycling, etc).

But I think that the situation you are posing: quasi regularly driving a trip that is >100 miles with no ability to charge at all is actually pretty uncommon. And even in your case, since you are driving that far (and visiting family), I assume you are staying overnight. You can get a portable lvl 2 charger for a couple hundred bucks that will plug into a dryer plug and charge your vehicle back to full overnight. (admittedly. this assumes the drive is in ideal conditions and you get the full 210 miles; given where you are going and the apparently lack of infrastructure, if this is mountainous at all, then yeah....very well might not make it)
To me, the issue that actually affects more people is that if you need a family sized vehicle, your options are A) pretty limited and B) almost all >$60,000. For a single person, or a childless couple, EVs are pretty accessible, for families, that's much less true.
For anyone not trying do to both kids + dogs, there are probably a lot more options.
Not everyone's use case is the same.
My laptop, power tools and iphone beg to differ....
Not sure that's true. I have seen comments on HN multiple times over the years claiming batteries die in a few years and were almost never downvoted.
Car batteries - very unlikely. Cheap portable electronics made in China - all the time.
The problem with these comments is that there are at least 10 different battery chemistries, and dozens of potential use cases and duty cycles you can put a battery through.
So yes, some combination of that will make batteries die in a few years. Most won't.
