[Talk-GB] Mapping School Streets

[Jez Nicholson]

Much as I like the idea of being able to see the full scheme in one place
(in a relation), it does rely on additional knowledge of said scheme rather
than observations on the ground.

If the mapping of the scheme is built up piece-by-piece by observing road
signage it makes modelling as individual turn restrictions more palatable.
