Presumably he could have just followed the road he was on and maybe reached town before freezing to death.
And all conventional wisdom says to stay put if you find yourself in a situation like that. Years ago I was listening to the local radio on my way to Denver when a big storm was coming in and they were talking about how many people die in blizzards every year with most of the deaths being people who tried to walk to safety instead of staying in their stuck cars.
More presumption but I’d say the standard thing to do in that part of the world is to just hunker down and wait until the next traveler comes along — or press the magic button on the iPhone and get to town before last call.
—edit—
And damn straight I’d be pushing that button if I got stranded.
