My dad was just talking to me the other day about how he has been watching videos on YouTube about these companies that have to drive out in the desert and rescue people when they get stuck in their 4WD vehicles. Apparently they have made a really good living off it. I think if I were to do something like you are talking about I would want to do it in tandem with one of my friends. That way I would at least have someone to have my back. If we both get stuck though...
Travelling in convoy is much safer for sure. To do the more serious stuff like the kads do in the videos I linked us actually essential. I'll be travelling solo though one vehicle), and that means some of the more challenging locations won't be attempted. It's a safety thing...and recovery (like you mention) is very costly.
That makes a lot of sense.
