Whilst in York, I was able to photograph some bus stops, I've done a
quick comparison of the data, it seems to be the worst in terms of
standards compliance so far, but seems to be quite self consistent,
which is a small bonus.

Why quote the above? Well, it seems that York is unaware of the
existance of the StopArea principle. (At least, I couldn't find it in
a quick grepping of the data).
