To help internationalize a dashboard app, I'm writing a small API that takes an ISO 3166 country code and returns which side of the vehicle the driver typically sits on. (Of course there may be oddball imported vehicles in any country; those will have to be treated specially.)
This page says (emphasis added):
Almost always, in countries where one drives on the right-hand side of the road, the cars are built so that the driver sits on the left-hand side of the car. Conversely, driving on the left-hand side of the road usually implies that the driver’s seat is on the right-hand side of the car.
I find similar hedged statements elsewhere. My question is, which countries are the exceptions to this rule?
