Only if the track has no other access. Said access may not yet be mapped
in OSM. 2WD can also be used to get from one end of the track to the 4WD
section, even if it can't be used to traverse the 4WD section.

What's the difference between "NPWS sign states 4WD only" (You can be
fined real money for disobeying these signs), "You'd be crazy to drive
a Commodore down here" and "Holy shit, how'd that Commodore get here?!".
The tagging guidelines page isn't clear about this and people in general
have no idea about how far you can really drive a 2WD if you're
determined and skilled. Conversely, people in general have no idea how
easy it is to get stuck in a 4WD if you are not skilled.
Also, contrast tricked-out Toyota Landcruiser with Subaru Forester with
2WD rally car. These vehicles, ignoring driver skill, have vastly
differing off-road capabilities. The 2WD rally car will go places the
4WD Forester won't. Clearly the Forester isn't a serious 4WD like the
Landcruiser, but the rally car isn't 4WD at all. How to indicate that
the Forester isn't suitable for a particular track?
The 4wd_only tag lacks any of the expressiveness needed to solve the
problem and the tagging guidelines don't address it either.
