The vast, vast majority of Americans don't live in "remote areas". They live in towns with infrastructure
Incorrect. The vast majority of Americans live in suburbs, and drive 10-30 miles around their home in order to get groceries, shop, go to the doctor, school, and gas up their cars. But the DO NOT WORK where the live. Work is 14-45 miles away, and the traffic on the commute is murder due to congestion and crazy drivers.
The country with the highest EV adoption in the world is Norway
I don't know that battery performance and degredation is linear with respect to colder temperatures. Much of the US (some of the most highly populated parts) has weather that is near or way below 32 (F) for some of most of the year.
And in Norway, those people are not doing anything remotely like the daily commutes of the USA. Their workplace is in close proximity to their homes. Because it's fucking cold in Norway and there are not (compared to the US) many people at all, and they live right in or next to the few population centers where they also work. Apples and Oranges.
That said, EVs (newer ones, anyway) can work just fine for a typical US commuter. Even though you might drive 100 (or 200) miles every day, the EVs can do that. Even in the cold weather.
There are two problems why people in the USA are not adopting EVs.
FIRST is that there is no charging infrastructure. If you don't own a home, you're just not going to be able to have an EV. And many many people live in an apartment/condo, and have no way to charge. You're going to have to fully charge every day. Oh and by the way, that's not just one car. It is almost always two cars. And if you have kids, now it's three cars. Or more. If you own a home, you probably want to install an actual charger. (Or three chargers!) More money. Maybe you can get solar and huge batteries (that can also help in home power outages, which happen a lot in some places). That is another big investment. Money, money, money.
SECOND REASON: Americans do not go on "road trips" a few times a year. They make drive on a 1,000+ mile road trip once or twice a year. But they are going on road trips almost every weekend, driving to all kinds of places that are 50-150 miles away. Those places don't have chargers, either.
