Not by half. There's a reason you are told to stay at a crash site. You survive. His wife and kids stayed, they are alive. He didn't stay, he's dead.
Most searches will be conducted by air, as that's the fastest way to cover the most ground. A car in a ditch, cleared of snow, is easier to see than some fool jumping up and down, or worse, unconscious.
To speak somewhat ill of the dead, he was a fool, not superman. Being a few miles from some sort of communication or shelter is one thing, but they knew they were nowhere. He should have stayed.
