I think that it's much easier to enforce a simple blanket rule than a
more complex, nuanced rule that varies with time, circumstance and
location. It was the same with the smoking ban: rather than just ban
it underground, it was banned throughout the TfL estate, so you didn't
get arguments about whether no smoking signs were visible or whether
Earl's Court District line platforms were underground or not.

So, yes, the real desire was to ban drinking from, say, city centre
trains and buses after 21:00, but it's easier and much simpler to just
ban it everywhere, at all times.

As far as I'm concerned it was Johnson's attempt to 'do something' in
transport, it was very early on in his first term. I didn't see the
need then, compared with general litter, feet on seats, window etching
(now almost absent) and I don't see it now, but then I don't often use
anything beginning with 'N'.
