I think we agree on motorcycle=yes on this but I'm not too sure whether we
use highway=footway or highway=pedestrian. (Which Sakar mentioned in his
reply).

I would personally prefer highway=pedestrian for the following criteria.
a. if the road is as wide enough as a normal road but people use it only
for walking (usually city centers, squares, etc),

highway=footpath
b. The narrow gallis and shortcuts which cannot have a car (sth bigger than
a maruti may be because maruti usually can squeeze in any kind of road)
move through it. Like the gallis in Bhaktapur or Kathmandu.

IMO, a living_street has low volume of traffic and usually have more people
activities, like mentioned in the wiki, children could be playing in the
field, or in Nepal, bunch of people gambling or a 24 hours bar (local
bhatti ;-) ) and people sitting in front in chairs drinking milk tea or
sth, etc. A highway=residential is more for people just using the road for
moving from one place to another.
And yes like you said, two way traffic vs only one car at a time is also a
nice way to classify the if it is living_street vs residential. Just a
note, the one way should probably be a result of more human activities
involved?
