That's a small adaptation, once you've got the basic concept. Obtaining the basic concept appears to be highly variable and difficult.
Funny enough, in London, it's move on the left on an escalator. Pass on the right if you're a car. And mayhem if you're a pedestrian on a sidewalk: half the people dodge to my left in a head on conflict, the other half dodge to my right. I see no pattern (maybe locals vs foreigners).
