"Car parks" is a unit as valid as seconds or meters.
Difference would be it has no dimension.

capacity=* goes far beyond car parks lots with school, hospital, hotels and
even benches capacity.
Pipeline wiki page should be improved to default capacity in m3/s instead
of free text although giving unit in values isn't an issue

Most values has no unit means wiki default applies.
Instead of using flow_capacity, what if wiki page for fire_hydrant defaults
capacity in m3/s ?
