Interesting. I don’t have a car any more and no kids, but my friends that do always tell me their kids need more breaks than the electric car. And I always found that I need breaks every 2-3 hours anyway to keep the alertness high. I can’t imagine going 400 miles in one go.

and often 800 miles in a day (takes about 13-14 hours driving)

Oh wow. After my last trip that was supposed to take like 9 hours and ended up more like 12, I decided to never do that to myself ever again. But I guess if you have multiple drivers that can share the burden, such along day on the road is still an option.
