True, unless you are an X owner towing a trailer. As I will be next year. In that case, if I want to camp in Yosemite Valley at the Upper Pines Campground I would like a charge to ensure I can get back to Groveland. It’s only a 100 mile round trip, but towing really impacts range, there are significant elevation changes, and the car will lose charge sitting for several days, plus nights are cold.
The Fish Camp to Upper Pines Campground is only about 70 miles, so a bit easier. But I like to maintain a generous safety margin especially when traveling in the mountains where charging options are extremely limited.
