As someone that wants to go on ski trips, it's the exact nightmare scenario for EVs. In nominal conditions it's a long, cold trip with lots of people inside, lots of shit in the trunk, and potentially stuff on the roof harming aero greatly, while also being cold and driving through mountains with potentially limited fast charging. Oh and god forbid the road gets shut down and you need to stay in the car for a few hours as they drag out someone from the ditch!

What’s the difference for being stuck in the cold in an EV to an ICE car? The time you can keep the heating running is very similar (around 1,5 days with a full tank of gas or a full battery). The only benefit of the combustion engine is that you can keep some extra fuel in the trunk. But who has 50l extra fuel in their trunk?

  Setting aside the cold, being stuck in general is easier to recover from in an ICE car. It’s very easy for AAA, emergency services, etc, to bring you a container of gasoline at the side of the road. I honestly don’t know, what’s the solution for EVs? Will AAA bring a generator? Can they charge you off the engine of the tow truck?

    Yes, you can charge an EV from a generator, there are already devices for that on some service trucks. There is another option (although not recommended by any manufacturer): If the EV still goes into drive mode, just tow it for a short distance and use regenerative breaking. You should be able to gain 2-5 times the towed distance as range. Edit: this technique is not recommended, although it seems to work. It’s very important that the car still turns on and you can select D. Otherwise the car may get severely damaged. If the car is off, it should not be towed more than about 5 time its length. When you tow it, there is a lot of electricity generated in the engines, even if it’s off. (There are exceptions from this rules though).
