That is not an easy drive in the winter, and if you're going at peak times, there can be major delays. I have never driven that road in an EV, and it's been 25 years anyways, but I once got stuck on Donner Pass in a blizzard. We didn't have to eat each other but the ride from Tahoe to SF took 11 hours, a lot of which was literally just being at a standstill for several hours. People were getting out of their cars and having snowball fights on the highway. I sure hope there's a lot of charging infrastructure there now, because that road, in winter, with a child, would give me massive range anxiety.
I'm not knocking the use case - far from it. Just saying it's a challenging route.
