My husband and I took a road trip of 4,682 miles in a Tesla, with a dog. We stopped every 3 hours and charged for 30 minutes. It was not only possible, but easy, because those stops corresponded to lunch, coffee, dinner, and sleeping. The dog needed to be let out, I needed to stretch my legs, etc.
It's harder with kids. Tesla gets a reasonable range due to squeezing everything to the limit. Getting the same range out of a minivan-sized vehicle without tripling the cost of batteries would be rather tricky.
Also when you travel with kids, you make longer breaks when the kids need them. In that case, picking a random gas station nearby filling the gas while my wife runs everybody through the toilet and distributes snacks, makes things easier. Doing it exactly on schedule with a forced 30-minute wait in a fixed location would be much trickier.
