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.

I don’t know how remote your mountains are, here there would likely be a charge point less than 50km away but I don’t know where you drive. I give you that.

Your second point though, you might want to reconsider your driving habits. Random google result for breaks when driving: “If driving long distances, you should stop for at least 15 minutes every two hours. Stop often to rest for at least 45 minutes every 4.5 hours of driving to avoid getting tired and stay alert. Plan to stop for a break every 100 miles on your long road trip so that you can relax. Try to only drive for 9 hours a day.”

How so, I’m curious? Do you drive into no mans land hundreds of miles away from civilization or are you a robot that never needs to take a break?
