In the mountain West of the US, there are semi-frequent major highway closures due to weather conditions, serious accidents, etc. It is not uncommon for the shortest paved detour to add 120 km to your trip. That's not a big deal in an ICE vehicle, since every one-horse town near the detour route has a gas station. That fact has saved my bacon several times even with proper planning. People who live out there are accustomed to this reality. Adventurous people can sometimes find much shorter alternative routes using ranch/mining/forestry trails but those don't always exist and you definitely won't be driving your Tesla on those roads.

The worst detour I've experienced in recent years was a serious accident in the middle-of-nowhere Utah, which closed the highway in both directions for almost 24 hours. The shortest paved detour around the accident added 150km of nothingness to the trip.
