...as in Europe (but I am certain there are exceptions and am looking forward to the replies pointing out where that is not the case)

Berlin uses a different system in the older parts of the city

Wikipedia describes two systems in the UK: https://en.wikipedia.org/wiki/House_numbering#United_Kingdom

According to both those systems, if you look down the street from the end where number 1 is (which is always the open end of a cul-de-sac), then number 1 is the first house on your left. I'd be interested to hear about any exceptional cases in which number one is on your right.

I don't know of any country that uses an entirely different system, but I'm willing to bet each country has a couple of exceptions somewhere.

IIRC, Japan uses (or used?) to number buildings in chronological order.

Our machines have been possessed by daemons for years so I'm not at all worried.

That is not a strict rule. I grew up in a neighborhood where houses were numbered by the order the lots sold. They were effectively random.

I know. I grew up on a road with no name that numbered the houses with an odd cadence. But, well mannered neighborhoods have stuck with the scheme such that most people recognize the reference.
