I've added my comments below Andrew's. Hope that is not too messy. /Mike

Like my previous post on sidewalks, this one is also from walking and
cycling all of the streets of my LGA (Willoughby). The other area
where
tagging seems to me to be a bit messy is:
highway=service
This messiness may be more of a general OSM issue than
specifically an
Australian one!
Where possible I've been trying to add a service=? tag to define
these
better, in line with the relevant pages on the wiki. In my area, the
majority of these seem to be:
1. laneways between houses -> service=alley
For me these are part of the official road network, but in Willoughby
they are normally narrow, and lead to/past people's garages. This one
seems relatively clear cut - and also appears to be the only
service tag
that does relate to the official road network(?)
Yeah I'd agree, but these are part of the public road network, they
are just lesser importance roads because they are mostly for access to
the rear of houses.
+1. And in the US and northern UK may be poorly maintained, cobbled,
temporarily obstructed etc, a good flag to routers.
2. driveways (private property) -> service=driveway + access=private
This seems pretty clear cut in residential areas. It also seems
fairly
clear for small business/industrial property that are for
employees/business vehicles only.
Where it gets a bit confusing is if the driveway is to something
else.
For example, in the Willoughby area, there are many industrial
complexes
which have "driveways". But if it leads to parking
(amenity=parking?),
is it still a driveway, or is it just highway=service without
service=*.
The access=* issues also interplays with this - because in larger
industrial complexes there may be a mix of access=private and
access=customers.
Can you post examples? In my opinion, a good rule of thumb for
driveway is where you need to turn off the road and cross the
footpath. I realise it's not always clear though.
Technically only the section inside the front fence is private, the
section between the footpath and road is public but I've never mapped
to this level of detail.
Personally, I ONLY use driveway for residential driveways. I feel using
it for anything else is confusing and adds no value - despite what Map
Features says. Like Andrew, I rarely split the sections into private and
public sections but it IS useful for foot and wheelchair routing.
3. parking areas
This one can also be a bit confusing - following the wiki, some of
these
end up being service=parking_aisle, but others are without
service=* eg:
https://www.openstreetmap.org/edit#map=19/-33.80928/151.20897
<https://www.openstreetmap.org/edit#map=19/-33.80928/151.20897>
I imagine you can do in theory do an area query to establish
highway=service within amenity=parking, but this does seem clunky!
And not that we should be mapping for the renderer, but the rendering
also seems inconsistent:
https://www.openstreetmap.org/#map=19/-33.80939/151.20923
<https://www.openstreetmap.org/#map=19/-33.80939/151.20923>
If you can turn from the way directly into a parking spot, then it
should be parking aisle, so that one I think should be parking aisle.
Slightly different view here. I find that most car parks have "arterial"
ways for ingress/exit, navigation within larger parks, and sometimes
very local through "destination" traffic; obvious from design or width.
I don't put a parking_aisle on these. I think leads to better map
presentation and routing. In Melbourne, I find that many car park
service roads double up as useful bicycle connectors.
