I think this is basically wrong tagging.

Broadly agreed with your concerns.

A very important characteristic of a place you can drive is

  - it is legally a road, where more or less anyone has a right to
    drive (and this can be public ownership or private).  Typically this
    means that the ground on which it is built is carved out as a
    separate lot for ownership (or government owned).  This can be
    government, or it can be a road in a subdivision which is in the US
    marked "private way" meaning that it is legally a road but privately
    owned.  You can still get a speeding ticket on it, because the road
    use rules apply to private ways, but do not apply to what you do in
    your farm field.

    Whether they apply in a shopping center is an interesting question.
    I'd say: yes, you will be cited, and probably that does not hold
    up.  But in some places (north carolina), the property owner can put
    up signs that the traffic laws apply anyway - I saw these at the
    biltmore estate.   Basically "this is private but the unwashed
    public is here and we want the police to be able to bust them" :-)

  - not legally a road, in that there is no right of access, traffic
    laws do not necessarily apply, and there is no separate parcel for
    it

This is basically
"highway=primary/secondary/tertiary/unclassified/residential" vs
"highway=service/track".

It would be goo to have this be

Mostly agreed, but that's not quite right.  It's "a legal road" vs "a
place you can drive on someone's property".  If the pavement (assume
paved, but that's not the point) is on land owned and maintained by the
government, even if it only goes to one house, it's a road, not a
driveway.

I don't quite follow - but agreed that if no right of way it's service/driveway.

That's a clue, but having a name on a service road is not proof of it
not being service.   My town has an airport access road which sort of
has a name, but is on a private lot and really a service/driveway.

no, it's special - not a legal road, and typically should not be used
for through routing.

typically not, maybe almost never.

typically yes, but it's not exactly the right test.  I've seen a
residential legal road with more or less one house, but a separate land
area for the road, just like roads with more than one house.
