The driver suffered from bouts of paranoia as part of his condition. He likely led them into the mountains to escape from one of his delusional pursuers and they got lost because it turns out a man who is both retarded and paranoid doesn’t make the best guide through a cold forest 

Why someone like that was allowed a car and put in charge of others, even for just a day trip, I have no idea

Yeah I don't think how they got there is very mysterious. They took a wrong turn and ended up in the middle of the woods. A couple of retarded decisions later and voila they're all fucked and lost. I do think the hut with the rations are odd, even a borderline retard would start gnawing on a ration can once he starts starving even though he might think he's stealing.
