It's a tough situation to be in, on either end of it. Some things are not worth the risk, and some things are. "Pilot in command" is a big responsibility. You can't make the call for another, unless they really appear to not be able to make a reasoned call in the first place. At least the area is relatively flat, and visibility was relatively good under the scud. Stakes were high all around (though as always it could be argued that a commercial flight, or a rental car, would have been safer and gotten them there more quickly than waiting for the weather)

These folks discussed all options, and decided to wait it out. There
are no commercial flights to where they were headed, and rental cars
were priced out of sight.

The fellow had a tough nut to crack, and he apparently chose well.
