Italy is often entertaining. It seem like Italians believe as long as the horn is beeping when they hit you, whatever else happens is on you.
Iraq, Kuwait, and some parts of Saudi have a very "Inshallah" feel to the driving. We're going to do 180 mph, and drive wherever we want with no signals. If something happens, it happens. If the car is broken, we will buy a new one.
Southeast Asia is just very very crowded in the cities and jungle tracks outside of them. So like the worst posiible traffic you can think of, then add bicycles, tuk-tuks and mopeds weaving through, plus 5 lane roundabouts.
Africa is......Africa. I've only driven in East Africa, and it was what you would expect if you gave rednecks with no training Land Cruisers, shitty roads, and no accountability.
The US, UK and Western Europe does have the Caravan Menace, which adds to our sportiness, especially outside CONUS where two lane highways can go for a couple hundred miles. People will make poor passing decisions rather then be stuck behind a Caravan for 3 hours.
To the OP, I do remember laughing every year I lived in Alaska as the first couple snows hit and folks went ditch diving. I would always go up to the High School parking lot near my house late at night after the first snow and slide around a bit to "retune" my reflexes to snow driving.
FWIW Phenom Penh was the worst place I've driven for traffic, followed closely by Bagdad (when not in a tactical vehicle. An MRAP makes traffic less of a big deal.)
