People don't spend all that much time outside and when they do, they wrap up well enough that you don't get very cold.
These hypothetical cold fat burning technqiues, that I've seen, suggest inducing very mild hypothermia (shivering). That only happens rarely in the north.

Are you certain of that? It gets really cold here and everyone wears jeans. Only children wear winter pants casually. Sometime the air itself is cold enough to get you shivering.
The only time I see people correctly dressed against the cold is when they do winter sports or go hiking in the woods.
I think it's the opposite, the colder it is the more people heat their homes / cars / dress very warmly. They probably get the least cold exposure naturally.
I grew up in Toronto but I was always much colder in winter when living in Sydney. No insulation, plus vents in the walls and single pane windows mean it's warmer outside but much colder in.
