I always thought that driveways to private residences and private
roads (whether gated or not) should be tagged as access=private.
Often these private roads are posted with a sign that says something
like "Private road, no trespassing", or "Private Road, Residents and
Guests Only."

As I said, I tend to remove access=private if I DON'T see any barrier or
signed restriction during a survey. If I see see "private" or "no
trespassing" I certainly wouldn't. This is consistent with OSM
verifiability standards.
I feel the most appropriate default tag for driveways would be
access=destination, but since generally they are short dead ends it
rarely seems necessary. But there do seem to be many driveways tagged
access=private. Some from TIGER (which certainly can't be trusted) and
some from humans, sometimes using Facebook's RapiD.
Here's an example of how access=private on a driveway causes the routing
problem I'm talking about:
https://www.openstreetmap.org/directions?engine=fossgis_osrm_car&route=41.9288%2C-74.0024%3B41.9157%2C-74.0290#map=16/41.9168/-74.0237&layers=N
There's no access to the house at
https://www.openstreetmap.org/way/263869602 (forgive the poor building
mapping, not mine! ;) from Linderman Avenue. The correct is approach is
from the driveway https://www.openstreetmap.org/way/791633657 but that
driveway was marked as private by the mapper who added it (one of
Amazon's paid mappers, using RapiD.) The source list (always the same
long list of sources with the Amazon mappers) includes Bing Streetside
but I don't see any reason that this driveway should be marked private:
https://www.bing.com/maps?osid=fd2b22c5-aaed-46f5-8128-a64aaf15c84b&cp=41.91594~-74.029559&lvl=19&dir=106.782906&pi=-7.023267&style=x&mo=z.0&v=2&sV=2&form=S00027
If I surveyed a location like this and deemed it appropriate to remove
the access=private tag from the driveway, I believe that would benefit
the map.
