It can be a track indeed, my choice would depend on actual width. It's
impossible to be sure if a standard car fits it from a fixed photo,
perspective can be tricky at such assessments.

The wiki articles on mtb:scale and sac_scale state very clearly that
these tags can be applied to both tracks and paths. It's been years
that JOSM has had presets allowing these combinations. And it seems to
make sense since some tracks (and even normal highways) can be really
rough and deserve non-zero values for mtb:scale and sac_scale.

sac_scale can also be used on footways (says the wiki). In the
Brazilian context, this makes sense since we have decided to use
footways for paved foot paths and path for the unpaved ones. Some of
our footways (often sidewalks) have terrible pavement quality and are
worthy of non-zero sac_scale. Specifically in Brazil, since footways
can be used by bikes, they can also get an mtb:scale eventually.

Tracktype is often used on non-tracks too, says the wiki, and there's
a statistic there showing people have been combining it with paths too
(and more often than with residential streets). At this point, I'm not
contesting this tag anymore; rather, I'm trying to understand how is
that people understand it and use it.
