Must have been - interesting - when combined with the ‘wrong side of the road’ thing.
It was a bit intimidating, even for the locals.
I never did too bad with the left hand side thing, even in cities. It was when I was out on a two lane road in the country and had to move over the right side for one reason or another (passing parked car, etc.) was hard because I sometimes found myself staying on that side out of habit....hard to break.
