As I come from a more rural background, I developed my skills while hiking out to camp/hunt. And I still default to much of it even when exploring by vehicle.
Since the resurgence of the "bushcraft", "tactical", and "survival" fads in popular culture, I think a little too much weight might be being put on the necessity of it all, but there's certainly plenty of basic skills (knots, structures, rudimentary survival, etc.) that definitely have a place in the vehicle based travel realm.
*Now for the necessary disclaimer. This isn't to diminish formal skills and training for those in the armed services, SAR, and otherwise. It also isn't to demean anyone who has interest in learning, practicing or teaching said skills. There is no judgement on my end. It's merely an observation that the vast majority of folks will/should have little practical need for much of it, for better or worse.*
I'm still a hammock-er myself, so setting up camp usually consists of at least one standard tarp or rainfly lashed in some fashion to match the weather (cold, wet, and/or windy). It also consists of some type of camp fire (season dependant) built and styled to match what I need from it. On my trips, I'm usually the more "rustic" of the group, lol. But the level of those skills I pull out of the bag is definitely dependent on the preparation and planning of the trip. With enough prep, I find much of the wide catalog of bushcraft/survival skills becomes very much optional.
