For the blackout concerns: if you have solar panels, irrelevant, actually you'd be in a better place than with an ICE car. Also, if you have a garage, a fairly powerful generator cost peanuts compared to the price of a car, and some can run on gas cilinders and gasoline. Way safer to store gas cilinders than gas.
Long drives. Decades ago I drove with my ex and my in laws from Madrid to Brussels in one go. 2 of us taking turns.I swore to never do more than 800 Km in one go. We did it in a largish car, pretty comfortable. Yeah, no.
