1. The EV always starts. If it's below -20, our gasoline car may not.
2. The battery is always charged in the morning. OTOH the gasoline car is only filled sporadically. In the winter I try and ensure there's at least half a tank for safety reasons, but sometimes it does get as low as a quarter tank. Even with cold loss, an EV with a full battery has far more range than a gasoline car with a quarter tank.
3. The EV can be preheated in the garage without killing people.
4. An EV battery has enough capacity to run the seat warmers for a month, keeping people alive in an emergency. A gasoline car can only idle for about 24 hours.
5. That's if you keep your exhaust clear. I know people who didn't, and died.
6. A EV that's plugged in, but not inside can be kept warm.
7. Our EV handles a lot better on snow and ice than the gasoline car. Perhaps it's because of weight, perhaps it's because it can do traction control with the motor rather than using the brakes.
