(wow). Not just in the wrong places, but they don't exist.

If it wasn't for the non-existent ones, I'd wonder if it was a simple
programming bug, and they'd all line up if it was fixed.

It's really just a technology demonstration to show what can be done
with the data - and also to visualise how good the data is! The
particularly odd bits of data most likely derive from random people
misunderstanding how to enter postcode data.

The postcode stuff isn't a core part of OSM, and is going to be far
harder to survey independently than streets themselves, which we're
doing reasonably well at in some places.

If you're connected with the project, could you get them to put in the
ability for third parties to mark data points as erroneous? Also, the data
entrants should be shown the effect that each new datum has on that map
before they approve it for permanent inclusion in the database.
