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.

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.

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.
