Yeah exactly. Once there is some infrastructure around it won't be a big deal if I need to stop for 10 minutes. We often do anyway.That’s the crux of the issue. OP said he has literally nowhere to charge on the way.
Worst-case scenario of “we had to make an unexpected charging stop on the way” wouldn’t bother even someone like me too much but that’s very very different from being stranded and then waiting for a tow truck over a holiday when they are busier and/or fewer available.
There is of course a gas station in every single small town on the way. Some day that will be fast chargers, just not yet.
