Well, this is why I don't like the highway=residential tag.

The definition of living_street is a bit vague in the wiki. A relevant
bit seems to be:
"Simply tagging them with something like highway=residential, max_speed=7,
motorcar=yes, motorcycle=yes, bicycle=yes"
Which implies to me that the living_street tag almost never applies in the
UK - The vast majority of our residential roads have a speed limit of
30mph, with newer ones tending to have a 20mph limit. Just about the only
roads you'll see in the UK with a 5-10mph speed limit are service roads to
amenities such as schools.
I don't know enough about the road systems in other countries to comment -
from your description, it sounds like maybe you have living streets (very
low speed limit) rather than residential roads (20-30mph speed limits).
As I said, I really don't like the residential tag (although I do use it
in order to be consistent with the rest of the map). For roads with speed
limits over 30mph I don't tag them with highway=residential, even if they
have houses along them.

As I've said before, I have no intention of changing any areas I'm not
involved with - I'm just bringing a problem to the attention of everyone
else since I suspect that Swansea isn't the only place affected.
The roads I am retagging in Swansea are not wrong "according to some
classification I came up with on my own" - they are wrong according to the
definitions in the wiki - things like 50mph 2 lane dual carriageways are
_not_ unclassified roads by any stretch of the imagination. The problem
is simply that highway=unclassified has been used by a lot of people as a
general "I don't know what the classification of this road is" tag because
up until recently there was no other tag to use for this purpose.
