If you’re going to visit family up in the backwoods, the options you listed aren’t really viable. At least not for us.

And I don’t think you can drive 8 hours before recharging. Say you have a battery of 120 kWh, which is absolutely massive. And let’s say you’re driving at higher speeds like 100+ km/h, maybe you’ll be doing around 20 kWh/100 km consumption rate (that might even be generous depending on the car, especially in the winter). Finishing the battery from 100% to 0% would be (units in italics) 120 kWh ÷ 20 kWh/100 km × 100 km ÷ 100 km/h average speed = 6 hours of driving. And then your car needs to be towed at 0 percent charge left. 🙃
