Yeah, that seems perfectly rational. There is nothing to hit on a deserted highway. Driving in traffic, on the other hand, is more stressful and has worse downsides.
Spinning out on a deserted highway and hitting a snowbank and getting trapped in your car kills a large number of people every year. Even with smartphones, calls for help can't always be responded to in time, resulting in death. (Have an emergency kit in your car if you live above the snow line!)
Driving in city traffic can be quite harrowing, but hitting another car at 20-30 mph isn't usually fatal. (Wear your seatbelts!)
The point that GP post was trying to make is that humans have different preferences, and what seems dangerous to one doesn't (and possibly isn't) dangerous to another. Humans are also notoriously bad at judging danger, eg some people feel threatened by the idea of wearing of papers masks.
