"all the vehicles are one the wrong side of the road"

The biggest problem with that, is in the Caribbean, the closest automobile supplier is the US, where all the cars are left hand steering. This means that when you try to pass someone, you have to get all the way out into the opposite lane before you can see if anyone is coming at you. In Nassau, at least, the coming drivers (mostly) are quite accommodating, and will pull to the side, and make a three lane road out of a two lane highway. It's when that doesn't happen that you can be in deep trouble.

When I was stationed in Australia, many of us brought our cars/pickups/vans from the USA. As you said, passing is problematic.

I went at least 20 miles down the Stuart Highway in South Australia right before Dawn when I finally spotted an oncoming vehicle's headlights. As he got closer (and the sky was brightening), I realized I was on the wrong side of the road since I left Woomera!

It really is in a almost unpopulated desert, but the Stuart Highway is the main middle North-South route on the entire continent (From Adelaide in the far South to Alice Springs and finally Darwin in the far North).

Luckily, still almost no traffic overnight except for Road Trains! And further lucky for me, the oncoming vehicle was just an old Holden (car). I'd HATE to hit a Road Train!

Typical Aussie Road Train. Some pull 4, even 5 trailers!
