Let's see if I understand you correctly. Your argument is that EVs can't work because
1. Most people regularly drive to places far from anywhere populated or any major highway.
2. They're driving so far into the wilderness, they can't get through on a single charge. Perhaps because they're driving through the wilderness in the middle of winter when their range is reduced (but by much less than 30% on most modern EVs--they've gotten a lot better in the last few years).
3. This isn't an issue for conventional cars because there are sufficient gas stations in the wilderness, and the fact that conventional cars also lose significant range in cold weather somehow doesn't matter.
4. Installing EV chargers at those gas stations is impossible because... well, no reason at all.
5. This is the normal case that applies to most people. We can't just say, "If you have unusual needs, you need to choose a car with a longer than usual range." All EVs need to be able to get through hundreds of miles of wilderness in the middle of winter in exceptionally cold climates or they aren't useful.
Is that really your argument?
Let's see. I've never in my whole life driven to somewhere that was far from population and major highways. I've never driven anywhere when the temperature was below -20 C because, like most of the world's population, I live in a place that doesn't regularly get that cold. I sure wouldn't drive into the middle of the wilderness when it's that cold, because that's an insane thing to do. If your car breaks down, you'll probably die.
Here come the edge cases indeed.
