You can be stranded in the middle of nowhere because a road is closed for many hours or days due to inclement weather or an accident and the detour is 100-200km beyond anticipated, with no charging possibility in between. Some parts of the mountain west have 200km between exits. Has happened to me multiple times. In some places and some times of the year, getting stranded legitimately risks exposure to the elements.
You can find a road impassable because EVs almost universally have poor ground clearance. If a road is closed due to conditions, per the above, the alternatives that are remotely reasonable in terms of distance may require high ground clearance to safely traverse. Again, I have been able to circumvent road closures for various reasons because I had a high-clearance vehicle. There are parts of the US where I will not drive without one.
Many years ago, I would routinely rescue people out of the Sierra Nevada in winter that had foolishly taken their (ICE) SUV on unplowed roads they were not equipped to traverse. You can die from exposure to the elements in that country, both winter and summer. An EV is much, much more poorly equipped for these types of environments. They were lucky I trawled for people on those roads (it was a hobby), they may not have been found for days.
tl;dr: high ground clearance and robust reliable range are serious safety features in the mountain west. Lack of it may find you stranded for days in difficult survival environments. Same reason I also carry ample water when driving through the same areas, just in case.
