A favourite trick of our local town planners is to build a residential cul-de-sac where the main roadway stops just short of the last few houses, but the road continues, after a change of surface, width and/or level, to give access to a few more houses. The effect can be seen in the Bing imagery at the ends of both branches of Haddon Close (http://www.openstreetmap.org/?lat=50.852612&lon=-1.199944&zoom=18&layers=M). Should the semi-private road extensions be mapped as part of the normal road, mapped but shown as private, or not mapped at all?

That looks to me like a shared driveway, which the houses on that section might have to jointly pay towards maintaining (thinking of somewhere I used to live here where that was the case - it might not be clear due to the trees but the last 4 houses on Cheriton Grove share a driveway). As such I would probably map it as a driveway (highway=service/service=driveway).

Edit: While I was there, I have now mapped the end of Cheriton Grove as a driveway, plus added the paths I used to walk in the area.

Well, there hasn't been a storm of protest from the OSM community, so I have mapped the roads as you suggested. The driveways in these examples are dead ends, so there are no routing issues. Thanks for your help.

Should nt the road be marked as private or tag it with permissive. For a stranger OSM its hard to find out if there a agreement for the use of a shared driveway. It could look public but no garantees and the sign prohibited / private or permissive could have fallen down. Theres a road sign for it in Europe Aanwonenden toegestaan / Anlieger Frei, if you have to go there for a message, your allowed (permissive). In general I think that we should be carefull with tagging roads without info and the more info the better.

If known, it might be appropriate to add an access tag, but a missing access tag wouldn't to me imply "access=yes", only that access restrictions haven't been recorded.

Also, these shared driveway type things generally go nowhere, so unless you are visiting properties on them why would you be going there? It's not like you'll be routed over them. I agree that access tags are useful where the information is known and without them incorrect routing might occur.
